Re: RAID 5 - unable to mount xfs volume

I am a bit confused. You have a hardware RAID controller but appear to be using mdadm software RAID?
CentOS 8 died a premature death at the end of 2021 - migrate to Rocky/Alma/OEL/Springdale ASAP.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are dead, do not use them.

Yes, that's how the setup was done. On the RAID Controller they are setup as RAID 0, then on the software RAID as RAID 5.

 You may be able to run smartctl on the RAID disks, something like this:
fdisk -l
smartctl --scan
smartctl -a -d megaraid,YY /dev/sdX

E.g.:
# fdisk -l
....
Disk /dev/sdb: ....
Disk model: PERC Hxxx
....
# smartctl --scan
....
/dev/sdb -d scsi # /dev/sdb, SCSI device
....
/dev/bus/5 -d megaraid,22 # /dev/bus/5 [megaraid_disk_22], SCSI device
....
# smartctl -a -d megaraid,22 /dev/sdb

Re: RAID 5 - unable to mount xfs volume

Yes, that's how the setup was done. On the RAID Controller they are setup as RAID 0, then on the software RAID as RAID 5.
Forgive me if this was done by you but that sounds totally idiotic. What is the point in paying several hundred currency units for a hardware RAID controller with battery backed cache and then not using it!

A consultant did the setup.

Have done a S.M.A.R.T check on all the drives and it seems there are two failing drive. Not sure if the second drive will hold if I was to replace one and have a rebuild of the RAID.

Re: RAID 5 - unable to mount xfs volume

Not sure if the second drive will hold if I was to replace one and have a rebuild of the RAID.
Depends on your available choices. If this is the only copy of the data on there (i.e. no backups!) then you don't have much choice. If you can mount it all and back it all up then at least you know you have a copy of the data.
CentOS 8 died a premature death at the end of 2021 - migrate to Rocky/Alma/OEL/Springdale ASAP.

CentOS 5 and 6 are dead, do not use them.

In a RAID 5 at most one disk can go bad.
Your XFS errors and seemingly two bad disks suggests that the RAID is
dead. Time for new disks (the old are 5 years)? RAID 6 plus hot spare?
And maybe a script that checks the disks daily and sends an e-mail if
there's problems?

A comment on the hardware raid 0 plus software raid 5.
Quite recently I tried to use twelve 16TB disks with a Perc H800
controller (raid 6 + hot spare). Did not work. Finally I read the
specs and it has a maximum 64TB raid size. Your H700 is in the
same family and may have the same limitation. If so, the hardware
plus software raid may have been used to circumvent this limit.
