 Posted: Fri Mar 15, 2024 3:06 am Post subject: errors with user quotas |
 |
|
Hi,
A long time ago, I set up user quotas on my /home. But for a while now I've had boot warnings telling me about obsolete concepts.
So I decided to start from 0 by following https://wiki.gentoo.org/wiki/Disk_quotas#Group_quotas_.28local_system.29
But is this documentation up to date?
If yes, why jqfmt=vfsv0 and not jqfmt=vfsv1?
I have the correct options in the kernel.
I activated quotas on the FS with tune2fs -O quota /dev/md126
In fstab I have:
| Code: | | /dev/md126 /home ext4 noatime,acl,usrquota,jqfmt=vfsv0 1 2 |
| Code: | /etc/conf.d/quota
RUN_QUOTACHECK="yes"
QUOTACHECK_OPTS="-avu"
QUOTAON_OPTS="-avu"
QUOTAOFF_OPTS="-avu" |
| Code: | # quotaon --print-state --all
group quota on /home (/dev/md126) is on
user quota on /home (/dev/md126) is on
project quota on /home (/dev/md126) is off |
| Code: | # LANG=C repquota -as
*** Report for user quotas on device /dev/md126
Block grace time: 7days; Inode grace time: 7days
Space limits File limits
User used soft hard grace used soft hard grace

| Code: | # LANG=C quotastats
Kernel quota version: 6.5.1

I can perfectly update quotas with setquota and edquota. Everything works, except that I have error messages that I don't understand:
First, the mount options do not mention journaled quota support (jqfmt option of fstab)
| Code: | # mount | grep /home
/dev/md126 on /home type ext4 (rw,noatime,quota,usrquota) |
And then :
| Code: | # rc-service quota start
* Checking quotas (may take a while)...
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option. [!! ]
*Starting quota...
/dev/md126 [/home]: user quotas enabled [ok] |
Or
| Code: | # quotacheck -u /home
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option. |
I don't understand what's wrong. |

Do you have quota support in your kernel ?
| Code: | File systems --->
[*] Quota support
[*] Report quota messages through netlink interface
[*] Quota format vfsv0 and vfsv1 support |

I'm sorry, I didn't read it. Unfortunately I can't help anymore; we need an expert for quotas.

That may be related to default behavior...
From the ext4 man page: | Code: | usrjquota=aquota.user|grpjquota=aquota.group
For journaled quotas (jqfmt=vfsv0 or jqfmt=vfsv1), the mount options usrjquota=aquota.user and grpjquota=aquota.group are required
to tell the quota system which quota database files to use. When the quota file system feature is enabled, journaled quotas are used
automatically, and this mount option is ignored. |
The man page also mentions that usrquota is the same as quota. Maybe try with only one of them?
Does tune2fs -l /dev/md126 mention anything about quotas?
Maybe strace will help? strace -f quotacheck -u /home
strace can be verbose, so it may benefit from using wgetpaste. For example, append the following to the command to save it to a file: 2>&1 | tee strace-quotacheck.out

Using usrquota or quota as option gives the same result. Both are in mount result.
Actually, only that line permits to mount /home:
(1) | Code: | | /dev/md126 /home ext4 noatime,acl,usrquota 1 2 |
With all others syntaxes:
| Code: | #/dev/md126 /home ext4 noatime,acl,usrjquota=aquota.user,grpjquota=quota.group,jqfmt=vfsv0 1 2
#/dev/md126 /home ext4 noatime,acl,usrquota,jqfmt=vfsv1 1 2
#/dev/md126 /home ext4 noatime,acl,usrquota,jqfmt=vfsv0 1 2 |
I have an error:
| Code: | LANG=C mount -o remount /home
mount: /home: mount point not mounted or bad option.
dmesg(1) may have more information after failed mount system call. |
And with (1), I get:
| Code: | # mount | grep /home
/dev/md126 on /home type ext4 (rw,noatime,quota,usrquota) |
I feel like I'm using 2 different quota systems (kernel and other) which means that although it works, I still get errors on a command. But what should I remove to no longer have errors and for it to continue working?
If I remove sys-fs/quota I won't have tool to manage anymore.
Should I simply remove /etc/init.d/quota at start ?
I realize that remouting a system doesn't remove quota option. To test, I added quota option to /var, but after removing the option in fstab and remounting /var, the option is still active.
| Code: | # grep /dev/md127 /etc/fstab
/dev/md127 /var ext4 noatime,acl,user_xattr 1 2
# LANG=C mount -o remount /var
# mount | grep /dev/md127
/dev/md127 on /var type ext4 (rw,noatime,quota,usrquota) |
This doesn't help to test. It's a server, can't reboot at each test.
| Quote: | | Does tune2fs -l /dev/md126 mention anything about quotas? |
Yes it does.
| Code: | # tune2fs -l /dev/md126 | grep -i quota

I was hoping it would have something more helpful.
The man page has options for --verbose and --debug. Perhaps one of those will help. There is also --interactive, which asks the user for input if there is an error.
--create-files mentions to create files, not read existing files. So I'm wondering if those files exist or if they are corrupt.
The error isn't particularly helpful as is, since it appears wrong.
The quota service checks all devices, which is where I thought the error was coming from, a device without quota support. Especially since it follows with 'enabled' for /home.
So hopefully one verbose, debug, or interactive provides something more useful.
