Thanks Peter, I haven't downgraded the kernel yet, and I think it's a great suggestion if I could report the bug to Redhat. I just don't know if it's worth my time to build a RHEL server. Instead, I'll probably disable quota enforcement, and write a script to replace the functionality. That way, I can add some useful features of my own ;).

I am certainly no expert on XFS disk quotas, but have you tried downgrading the kernel to see if it's a regression in the kernel module?
Do keep in mind that Rocky Linux 8.4 and 8.3 kernels are not signed for secureboot if you test this theory.

hi all, I hope somebody can offer some advice on a xfs disk quota problem, where the soft block quota grace period is ignored. I confirmed that the problem affects at least 4 file servers that I mgirated to Rocky.
On all servers, xfs disk quotas have worked correctly for over a year with CentOS8.4. Last month, I upgraded the 4 fileservers from CentOS8.4 to CentOS8.5, rebooted, then ran the migrate2rocky.sh script. The migration script reported no errors. This week, I noticed that quotas grace period was ignored. I changed nothing on the servers except upgrading packages/migrating to Rocky. Now when a user's soft block quota is exceeded, write access is denied (even though the user is within the grace period, and below the hard quota).
Below is information from one server, but all 4 are similar:
# cat /etc/redhat-release Rocky Linux release 8.5 (Green Obsidian)
# uname -a Linux fs8.priv 4.18.0-348.7.1.el8_5.x86_64 #1 SMP Tue Dec 21 19:02:23 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

[julie@fs8 ~]$ touch /export/716f9/julie/a touch: cannot touch '/export/716f9/julie/a': Disk quota exceeded
Can anybody offer some advice?
I tried the following without any luck:
removed the hard block disk quota upgraded all packages and rebooted downgraded quota-* rpms (from version 4.04-14 to 4.04.12 used rhel 8.3) and restarting rpc-rquotad (systemctl restart rpc-rquotad)
before downgrade # rpm -qa | grep -i quota quota-4.04-14.el8.x86_64 quotatool-1.6.2-13.el8.x86_64 quota-nls-4.04-14.el8.noarch quota-rpc-4.04-14.el8.x86_64
after downgrade # rpm -qa | grep -i quota quota-rpc-4.04-10.el8.x86_64 quota-nls-4.04-10.el8.noarch quota-4.04-10.el8.x86_64
Thanks! Julie
