Subject: Metadata CRC error detected at xfs_dquot_buf_read_verify
Date: Thu, 7 Feb 2019 13:09:38 -0300 [thread overview]
Message-ID: <201902071309.38999.ricardo.barberis@gmail.com> (raw)
Hello list!
I'm having a metadata corruption on an XFS filesystem, I googled the error but
didn't find anything about it.
Background:
One CentOS 7.6 box with 2 SSD disks and 3 SATA disks.
Those disks are synchorized via DRBD with 5 identical disks on another
identical box (for HA).
The SSDs form an LVM group with one VG and one LV.
This LV is then formatted with XFS and mounted with quotas enabled.
The SATA disks form another LVM group with one VG and one LV, also formatted
with XFS and mounted quotas enabled.
Each pair of servers has keepalived to make sure only one of them puts the
DRBD resources as primary and can mount the LVs.
Relevant extract from lsblk:

We have several pairs of servers with this same configuration, but on this
particular pair of boxes we're getting metadata corruption only on the SSD LV
and quotas don't get accounted for, dmesg shows these errors on the primary box:

We tried xfs_repair but it doesn't seem to fix it.
We then promoted the secondary and tried xfs_repair there, fearing some memory
issues on the primary, but the result is the same:

Is there anything else I can try?
Any more info needed?
Should I open a bug report instead?
I can compile a newr version of xfsprogs but I don't know if it'll help.
Thanks,
