And, in this case, newer tools have found a validity problem that the older tools and kernel didn't. You can use xfs_db to fix the broken alignment in the superblock, but I'd like to get to the bottom of where the problem is coming from first. > 02:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS-3 3316 > [Intruder] (rev 01) Ok, so it's an lsi/broadcom 3316 hardware RAID controller. Which means this is most likely a firmware bug. Can you update the raid controller to the latest firmware and see if the block dvice still reports the same iomin/ioopt parameters? If so, you need to talk to your vendor about getting their hardware bug fixed and ensure their QA deficiencies are addressed, then use xfs_db to rewrite the stripe unit/stripe width to valid values so you can continue to use the filesystem on modern kernels.
