Disk quota plugin error

[abhelou]

I can’t enable disk quota. my os is Ubuntu 24.04. during the fresh installation i got an error that it wasn’t enabled, now from panel when i try to enable the plugin i get “Installing required kernel modules for quota support…”
during fresh installation:

quotaon: Your kernel probably supports ext4 quota feature but you are using external quota files. Please switch your filesystem to use ext4 quota feature as external quota files on ext4 are deprecated. quotaon: using //aquota.group on /dev/sda1 [/]: No such process quotaon: Quota format not supported in kernel. quotaon: using //aquota.user on /dev/sda1 [/]: No such process quotaon: Quota format not supported in kernel. Error: quota can't be enabled in /

when i try to enable from panel i get “Installing required kernel modules for quota support…”
is there any way to fix this for per user quota ?

Show the output of these commands:

find "/lib/modules/$(uname -r)" -type f -name '*quota_v*.ko*'
dpkg -l | grep -E '^ii\s*quota'
grep -Ev '^$|^#' /etc/fstab

[abhelou]

root@server:/home# find “/lib/modules/$(uname -r)” -type f -name ‘quota_v.ko*’
dpkg -l | grep -E ‘^ii\s*quota’
grep -Ev ‘^$|^#’ /etc/fstab

You don’t have the quota modules.

Try to install them and show the output:

apt update
apt install linux-image-extra-virtual
find "/lib/modules/$(uname -r)" -type f -name 'quota_v.ko*'

@sahsanu

find "/lib/modules/$(uname -r)" -type f -name 'quota_v.ko*'

the module still not there and no new packages installed

I see you are using a specific kernel from Oracle, check whether an extra package for that kernel provides the modules.

apt install apt-file
apt-file update
apt-file search -x '6.14.0-1016-oracle.*quota_v.*.ko'

It should be a package with this name (or similar) linux-modules-extra-6.14.0-1016-oracle

[abhelou]

yes, it’s an oracle image

root@server:/home/ai# apt-file search -x '6.14.0-1016-oracle.*quota_v.*.ko'
linux-modules-extra-6.14.0-1016-oracle: /lib/modules/6.14.0-1016-oracle/kernel/fs/quota/quota_v1.ko.zst
linux-modules-extra-6.14.0-1016-oracle: /lib/modules/6.14.0-1016-oracle/kernel/fs/quota/quota_v2.ko.zst
linux-modules-extra-6.14.0-1016-oracle-64k: /lib/modules/6.14.0-1016-oracle-64k/kernel/fs/quota/quota_v1.ko.zst
linux-modules-extra-6.14.0-1016-oracle-64k: /lib/modules/6.14.0-1016-oracle-64k/kernel/fs/quota/quota_v2.ko.zst

[sahsanu]

Then install the right package and you should be able to use quotas:

apt install linux-modules-extra-6.14.0-1016-oracle

it worked. thank you
