12:39.06CaptnChaos# mount -t ubifs -o sync /mnt/rootfs.ubi /system/
12:39.06CaptnChaosUBIFS error (pid 724): ubifs_get_sb: cannot open "/dev/loop0", error -22
12:39.06CaptnChaosmount: mounting  on /system/ failed: Invalid argument
12:39.09CaptnChaosany suggestions?
12:42.53pyteydownload an ISO image and try mounting that first
12:43.11pyteyfor example an ubuntu image
12:43.52pyteyfrom http://www.ubuntu.com/download/ubuntu/download
12:44.34pyteythen do -
12:44.43pyteymkdir /tmp/mount
12:44.55pyteyand then -
12:44.55pyteymount -t iso9660 -o loop ubuntu-11.04-desktop-i386.iso /tmp/mount
12:50.20CaptnChaos# mount -t 9660 -o loop /mnt/gparted-live-0.8.1-3.iso  /system
12:50.20CaptnChaosmount: mounting  on /system failed: No such device
12:56.20CcSsNETooo new filesystem time to lookup
12:56.25CcSsNETgoogles ubifs
12:57.29CcSsNETo nice, jffs2 but newer

13:03.22CaptnChaoswhy is that mount cannot open /dev/loop?
13:04.40pyteyCaptnChaos: try what I suggest please
13:04.51pyteyOK, you did, sorry
13:04.58pyteydidn't see that in the scrollback
13:05.00pytey:)
13:05.30pyteyCaptnChaos: make another mount point /tmp/mount
13:05.39pyteylike I suggested
13:05.48CaptnChaospytey: already tried, tried to change owner and permissions, too
13:06.28*** join/#elinux vanner (~vanner@195.91.241.19)
13:06.39pyteyprobably the loop device isn't enabled in your kernel
13:06.46pyteyor the correct module loaded
13:07.08pyteywhat distro is it?
13:07.56pyteyCaptnChaos: which distro
13:08.34CaptnChaospytey: lfs, embedded, the problem with iso is found, didnt compile 9660 support
13:09.08pyteyprobably more like loopback support
13:09.29CaptnChaospytey: but ubifs support is compiled in.
13:09.46pyteymaybe it is, but loopback support isn't
13:10.07pyteytry the same operation on your desktop linux machine
13:10.15pyteyif you don't have one, get one
13:10.18pyteyor use a VM
13:12.41pyteytry this -
13:13.01CaptnChaosnope doesnt work there either
13:13.05pytey<PROTECTED>
13:13.09pytey<PROTECTED>
13:13.14CaptnChaoshm i used compression for the fs
14:12.22Russumm
14:12.29Russyou can't mount an ubifs loopback afaik
14:12.35Russyou need to mount it on an ubi volume
14:13.26Russyou'd have to use nandsim

14:45.39CaptnChaosRuss: yeah, thx, im using ext2 image for development now

15:47.02RussCaptnChaos, if you just want to make an ubifs, there is a special command for building ubifs images
15:47.31CaptnChaosno its not just an ubifs
15:49.00CaptnChaosi wanted to put it into an image cause i couldnt create devnodes in a nfs mount
15:49.21CaptnChaosand because i want to use ubifs later, i thought it could be nice if you already have it
15:49.54Russwho creates devnodes anymore?
15:50.02Russjust mount devtmpfs
15:52.31*** join/#elinux ZeZu (null@c-98-227-57-1.hsd1.in.comcast.net)
