Hello

There is a problem enabling disk quotas in Centos 7

System

uname -a
Linux 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

 cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[

In /etc/fstab

cat /etc/fstab | grep " / "
UUID=8e8c52d2-df1a-4158-b523-a8ca4574de36 /                       xfs     defaults,usrquota,grpquota        0 0

to /boot/efi/EFI/centos/grub.cfg

linuxefi /vmlinuz-0-rescue-28533b7e6bb04bcc911aa4557a6298e4 root=UUID=8e8c52d2-df1a-4158-b523-a8ca4574de36 ro consoleblank=0 crashkernel=auto rd.md.uuid=333195d5:ae669e81:bb847115:0d19eef6 rd.md.uuid=8c47a7bf:d9c7b041:2ac5473f:e85c1481 rd.md.uuid=0000f632:c9708856:413b88f0:52e2a86e nompath selinux=0 rhgb quiet rootflags=uquota,gquota

After restarting the server

mount | grep md2
/dev/md2 on / type xfs (rw,relatime,attr2,inode64,noquota)

Can you please tell me why else quotas may not be included?

In general, the problem turned out to be that my OS works with an mdadm-raid, but the UEFI partitions on each of the disks had their own. As a result, the grub config was corrected on one disk, and the OS started from another. Therefore, the changes made were ignored.

According to some documents on the net, xfs does not need gquota , but pquota

But I haven't tried it myself.

@vitaly_il1

did you run grub2-mkconfig?
By the way, I would first make sure that it turns out to mount a non-root filesystem with a quota.
