After upgrading to 6.12.1, the first boot was success and all drives are mountable. Then I restarted the server again, after the next boot, two drives becomes unmountable and log shows following error.


XFS (md1p1): Metadata CRC error detected at xfs_sb_read_verify+0x11e/0x1aa [xfs], xfs_sb block 0x0


I tried to run xfs_repair on two unmountable drive, it complete successfully but still cannot mount in array.

please close the post, I managed to rebuild the parity and fix the issue.


I am running parity and two disks got disabled but the parity disk is not sync so the emulated disk is corrupted for the metadata part which is written frequently. I am running fsck on physical disk which is not being used as they are disabled.
