We're running CentOS 5.10 at the moment, and I created a 15Tb ext3 filesystem on that RAID group (set this up a few years back) that has been running fine up until yesterday. I had the opportunity to add another PERC H810 controller along with a PowerVault MD1200 to add more space (44Tb as XFS), but when we went to turn the server back on, we noticed one of the disks in the RAID group had apparently failed. I didn't think much of it at the time, as it was a RAID 5, but when the server came up and I tried to mount it, I received the following error: > > mount: wrong fs type, bad option, bad superblock on /dev/sdb1, > missing codepage or other error > In some cases useful info is found in syslog - try > dmesg | tail or so > > I tried to get a listing of backup superblocks by doing the following: > > [root@raos_apps01 ~]# mke2fs -b 8192 -n /dev/sdb1 > Warning: blocksize 8192 not usable on most systems. > mke2fs 1.39 (29-May-2006) > mke2fs: 8192-byte blocks too big for system (max 4096) > Proceed anyway?

I ordered another drive to replace the failed on thinking that *might* be part of the problem, so I will have to wait and see on that, but I SHOULD be able to mount it, but I am not able to. Chances are the block size is either 1K or 4K. That's the problem. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: http://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
