Summary

0000988: mount does not support usrquota/grpquota options

Description

we are trying to get quota working on a reiserfs filesystem created on an md raid device /dev/md0. However, when issuing a mount command to mount the device with the usrquota/grpquota options, the following error message is returned:

mount /dev/md0
mount: Mounting /dev/md0 on /mnt/data failed: Invalid argument

this when using the following fstab entry:

/dev/md0 /mnt/data reiserfs usrquota,grpquota,noauto,noatime 1 2

when mounting without using fstab but by forcing the options on commandline, the command succeeds:

~ # mount -t reiserfs -o usrquota,grpquota,noatime /dev/md0 /mnt/data
~ # mount
/dev/md0 on /mnt/data type reiserfs (rw,noatime)

~ # quotaon -vug /mnt/data
/dev/md0 [/mnt/data]: group quotas turned on
/dev/md0 [/mnt/data]: user quotas turned on

HOWEVER, quotas aren't really enabled, users can do whatever they want with the drive, no limits is imposed.

When using util-linux's mount, everything works without any problems, by using the same commands as stated above, so this has to be an issue with busybox's mount.

Notes
(0005014) vda 02-18-08 04:04	Just added additional -vv output support to mount. With it, I see the following: # mount -vv /dev/sda6 tmp -o usrquota mount: mount('/dev/sda6','tmp','reiserfs',0x00008000,'usrquota'):0 So, "usrquota" is indeed passed to kernel. We did our part. Why quota isn't actually working for you - that's another question. If you can get additional info - for example, how util-linux's mount() call exactly looks like? (Not mount command, but mount() call done inside it). Is it different from what we do? How? Strace here doesn't help enough, you will need to build util-linux from source, find mount(...) call and add debug printout like this: rc = mount(source, target, filesystemtype, mountflags, data); + printf("mount('%s','%s','%s',0x%08lx,'%s'):%d\n", + source, target, filesystemtype, + mountflags, (char*)data, rc);
