| 21:08.24 | jsmith-busy | eightyeight: Did you try the "-C" (capital C) option? |
| 21:08.53 | eightyeight | no. is that the trick? |
| 21:08.58 | eightyeight | checks the manual |
| 21:09.30 | eightyeight | ahh. reading only from the cache |
| 21:09.34 | tyce | if you're doing an rsync from one drive on a sata controller card to a raid6 array on the same controller, shouldn't all the processing happen on the card itself? |
| 21:11.14 | goozbach | tyce: is it true hardware raid6 or is it the silly winRAID stuff? |
| 21:11.45 | eightyeight | tyce: depends on the controller, if it's a true raid controller card, or fakeraid |
| 21:12.15 | eightyeight | and depending on the rsync command, will determine what the cpu processes |
| 21:12.31 | eightyeight | using ssh and compression, for example, won't be performed on the controller card |
| 21:13.12 | goozbach | and rsyn has to read the files to memory then back to disk |
| 21:13.22 | eightyeight | indeed |
| 21:14.14 | tyce | I believe it's "true" raid6 it's a 3ware 9650SE |
| 21:14.39 | tyce | and I didn't specify ssh |
| 21:14.54 | tyce | or compression of any kind |
| 21:15.50 | tyce | I'm lucky to get 10 MB/s in the xfer |
| 21:16.00 | tyce | trying to figure out what my bottle neck is |
| 21:16.18 | eightyeight | raid6 isn't the fastest of raid levels... |
| 21:16.40 | tyce | faster then 5-10 MB/s though, I'd assume, right? |
| 21:17.42 | eightyeight | are you sure ssh isn't being used? rysnc uses it by default if the syntax is of '[host:]/path [host:]/path' |
| 21:17.57 | jsmith-busy | eightyeight: Another option is to set "metadata_expire=never" in /etc/yum.conf, and the do "yum makecache" when you want to refresh the cache |
| 21:18.02 | eightyeight | what does hdparm -t /dev/sda (or whatever your disk is) show? |
| 21:18.14 | jsmith-busy | eightyeight: (that makes it a lot more like apt-get and apt-cache) |
| 21:18.43 | eightyeight | heh |
| 21:19.02 | tyce | it's the same host, so i didn't specify |
| 21:19.08 | tyce | just paths |
| 21:19.20 | eightyeight | and the output of hdparm -t /dev/sda? |
| 21:19.35 | eightyeight | (for the raid6 disk) |
| 21:19.56 | tyce | one sec, it's thining |
| 21:22.38 | tyce | /dev/sdb: Timing buffered disk reads: 782 MB in 3.00 seconds = 260.56 MB/sec |
| 21:23.02 | tyce | killed the rsync and got : /dev/sdb: Timing buffered disk reads: 1040 MB in 3.00 seconds = 346.63 MB/sec |
| 21:23.23 | tyce | so yeah, a lot faster then 5-10 |
| 21:24.18 | tyce | ssh is only the default for remote connections, right? it's not trying to use it for local xfers is it? |
| 21:25.08 | eightyeight | it will use it for local as well, if you have localhost:/path as one of the arguments |
| 21:25.17 | eightyeight | localhost, hostname, whatever |
| 21:25.31 | tyce | only other thing I could of is the -v or --progress flags are being employed, but I'd hope they wouldn't bog it down that much just writing to the screen buffer. |
| 21:25.55 | eightyeight | what other flags are you passing? |
| 21:26.11 | tyce | rsync -av --progress arc/backup/ new/backup |
| 21:26.13 | tyce | that's it |
| 21:26.25 | tyce | nothing fancy |
| 21:26.56 | eightyeight | and neither drive is network-mounted. both local to the system? |
| 21:27.03 | tyce | correct |
| 21:27.47 | tyce | there are nfs exports on those drives, but I am not using them for the sync |
| 21:28.16 | tyce | and I killed everything I could think of which may be read/writing to them while I sync'd |
| 21:28.38 | eightyeight | curious, but what does 'dd if=/dev/urandom of=/mount-point/tmp.img bs=100M count=10' produce (assuming you can create a 1GB file on the drive)? |
| 21:28.56 | eightyeight | the hdparm is only showing reads. the dd should give you a rough estimate on writes |
| 21:29.17 | eightyeight | or you could use iozone, which you probably don't have installed. sweet tool for disk benchmarking |
| 21:32.02 | tyce | I was watching iostat earlier |
| 21:32.09 | tyce | I'll have to check out iozone |
| 21:32.29 | tyce | it's taking much longer then I would think to write that 1GB file |
| 21:33.42 | tyce | 10+0 records in |
| 21:33.42 | tyce | 10+0 records out |
| 21:33.42 | tyce | 1048576000 bytes (1.0 GB) copied, 197.724 s, 5.3 MB/s |
| 21:33.42 | eightyeight | do you have any failed disks in the array? |
| 21:34.12 | tyce | not any longer, I did a week or so back, but plugged a new drive in and its status has been "ok" since |
| 21:34.37 | eightyeight | how was the performance of the array before the failed disk versus now? |
| 21:35.37 | tyce | http://pastebin.com/uLdpQX70 |
| 21:36.40 | tyce | shortly after I set the array up initially, I had drive failure, so I can't answer that question. |
| 21:38.06 | eightyeight | my guess would be that the controller card might be bad, or one of the disks in the array could be causing trouble, even if it hasn't failed |
| 21:39.08 | eightyeight | i would do more troubleshooting on the array, and each disk (if you can- some controller cards have software for this) |
| 21:39.25 | eightyeight | but, in the meantime, 10MBps is faster than 0. ã |
| 21:39.53 | tyce | yeah, that was a thought in the back of my mind, I just thought I'd try to rule everything else out before going the hardware failure route. |
| 21:41.05 | tyce | I appreciate your time as a sounding board. |
| 21:41.09 | eightyeight | np |
| 21:41.22 | eightyeight | that card seems to be a highly ranked card. lots of positive reviews for it online |
| 21:41.55 | tyce | yeah, that's why I ended up going with it.. that and the price I found was hard not to jump on. |
| 21:42.34 | tyce | I was previously using mdadm and got to the point where I thought it prudent to upgrade. |
| 21:43.39 | eightyeight | i'm using linux software raid at home for a 4-disk raid 10, and i'm happy with the performance |
| 21:44.24 | tyce | what do you primarily use the array for? |
| 21:44.46 | eightyeight | mirrored backups and off-site archives |
| 21:45.48 | tyce | basic backups and file storage exports worked great for me, it wasn't until I started to use it to record HD streams OTA with MythTV when I noticed problems with the encodings |
| 21:46.15 | eightyeight | yeah. i would like to setup a mythtv box, but my wife isn't ready for that yet |
| 21:46.35 | tensai | eightyeight: my wife griped while I was spending the money to build mine, but she loves it now |
| 21:46.57 | eightyeight | tensai: yeah. that's what i've heard. they piss and moan about it, until push comes to shove, and they actually use it |
| 21:47.12 | tyce | LOL, I've had a bunch of friends tell me that until they bring them over and I show thier wives auto comm flagging/skipping... they all leave wanting it setup ;) |
| 21:47.25 | eightyeight | heh |
| 21:47.51 | tyce | plus mythweb is worth its weight in gold |
| 21:48.03 | tensai | commercial autoskip fails too often for me to leave it on |
| 21:48.16 | tyce | it's a binus that I haven't paid for cable in 8 years. |
| 21:48.22 | tyce | really? |
| 21:48.31 | tyce | I have it on and almost never have a problem... |
| 21:48.42 | tensai | certain shows are more problematic than others |
| 21:48.49 | tyce | are you allowing it to use "all available" algarythms to scan with? |
| 21:48.57 | tensai | yes |
| 21:48.59 | tyce | that was key for me |
| 21:49.19 | tyce | OTA HD or cable tuner cards? |
| 21:49.21 | tensai | ota |
| 21:49.25 | tyce | bummer |
| 21:49.27 | eightyeight | i'm lucky to have a 2tb backup. it'll be years before mythtv gets approved. heh |
| 21:49.41 | tyce | well, that's what the 'q' button is for ;) |
| 21:50.08 | tyce | if you've got the pc for it, OTA hd tuners are cheap! |
| 21:50.27 | tensai | has a hdhomerun |
| 21:50.29 | tyce | I've paid ~$25 on average for the 5 of mine. |
| 21:51.19 | mheath | Are there any Linux based TV appliances that support Netflix Streaming? |
| 21:51.40 | tyce | boxee? |
| 21:51.52 | eightyeight | a bigger want is getting the hardware to put my vonage behind asterisk |
| 21:51.55 | tyce | er... the boxee box that is |
| 21:52.09 | mheath | hmm, I guess Roku is Linux based as well. |
| 21:52.20 | mheath | I guess more to the point: can any of these systems be modified or customized at all? |
| 21:52.25 | tyce | eightyeight: nice, if I had a land line, I'd be right behind you in like there. |
| 21:52.31 | eightyeight | i would love to have more controll over who can and can't call me |
| 21:53.04 | eightyeight | tyce: we went the cell-only route, and spent 5x the amount of a monthly bill by going over one month. we then realized the value of a 'land line' ã |
| 21:53.32 | eightyeight | and with google voice, if anything, we could probably drop the cell phones now to pre-pay, and save serious cash |
| 21:54.23 | tyce | totatlly agrees. |
| 21:54.31 | mheath | My problem with Landlines was always my busy schedule. I have nothing against the landline service - and you're right, the unlimited inbound calls and unlimited local calls are awesome - but I'm never home to answer the phone. |
| 21:54.40 | tyce | just wishes he wasn't addicted to his iPhone :) |
| 21:55.09 | mheath | My only interest in Asterisk would be an IVR for home automation things. |
| 21:55.28 | mheath | But even that, I can easily do from my Android smartphone now. |
| 21:56.31 | eightyeight | i won't pay for internet on my phone, and the plans are getting more pricey, with more minutes |
| 21:56.39 | tyce | eightyeight: you said the name of that package was iozone? |
| 21:56.42 | eightyeight | i maybe use 100 minutes per month |
| 21:56.45 | eightyeight | tyce: yeah |
| 21:57.13 | tyce | iozone3 - Filesystem and Disk Benchmarking Tool |
| 21:57.18 | tyce | ah.. forgot the 3 :) |
| 21:57.24 | eightyeight | ah. yeah. that's it |
| 21:57.47 | eightyeight | i don't want 700 minutes for $50/month. i want to pay only for the minutes i use, and not a cent more |
| 21:57.58 | tyce | I wish they offered 100 min/month plans with unlimit text/net... I'd opt that route in a heartbeat |
| 21:58.12 | eightyeight | sprint has 7¢/minute plans for prepaid, and they can use your existing number |
| 21:58.21 | tyce | I text WAY more then I talk... |
| 21:58.37 | eightyeight | with options for sms as well. and data (which isn't of interest to me) |
| 21:58.47 | tyce | guess I need to be more speciif there... 100 min.. *iPhone plans :) |
| 21:58.58 | tyce | *speciifc |
| 21:59.00 | eightyeight | and if the prepaid phone has 802.11 atenna, i'm there |
| 21:59.13 | tyce | hahahaha... for sure |
| 21:59.14 | eightyeight | i'm surrounded by free wifi much more often than not |
| 21:59.39 | tyce | are there android/the like phones on the market yet with 802.11n? |
| 21:59.54 | tyce | my iphone4 is still g iirc |
| 22:00.39 | eightyeight | i'd purchase an android phone, if they'd sell it without the data plan |
| 22:01.22 | tyce | 802.11b/g/n Wi-Fi (802.11n 2.4GHz only) -- from specs page |
| 22:01.26 | tyce | ahh... that sucks |
| 22:01.41 | eightyeight | i don't know a provider that will do that |
| 22:01.44 | tyce | it's got n, just not the 5ghz band 'n' |
| 22:01.48 | eightyeight | heh |
| 22:02.15 | tyce | oh well, next summer :) |
| 22:03.58 | tyce | eightyeight: do you have any "favorite" tests you like to run using iozone (ie: flags, etc)? |
| 22:05.18 | tyce | these look decent: http://www.cyberciti.biz/tips/linux-filesystem-benchmarking-with-iozone.html |
| 22:05.50 | eightyeight | tyce: it depends on the system |
| 22:06.16 | eightyeight | i always do writes that have the next prime number above the number of ram in the system, to prevent full caching |
| 22:06.25 | eightyeight | other than that, i just poke around |
| 22:06.29 | eightyeight | clicks the link |
| 22:07.20 | eightyeight | i never do excel compatible output. i just parse the data in stdout |
| 22:07.51 | eightyeight | i've been meaning to tie it in with bonnie++, but i've never gotten around to it |
