Hi Guys,
I have a server running CentOS 4.2 with a 2.6.9-22EL-smp kernel.
The system contains a 2.3 TB RAID 5 array. There is a 20GB root partition with the remainder of the drive configured one large LVM volume. (/u0)
I have installed Veritas Netbackup on the server and am running a few tests. Small backups and restores work just fine.
When I run a larger backup (500MB) and store the backup file on /u0/vrts the files within the backup cannot be restored. I thought at first this was a Veritas problem but have also discovered...
I cannot do any of the following to the backup file: Use cat, dd or cp to copy the file. The first part of the file aproximately 24MB will copy and then I get the error message: Input/output error
Checking dmesg shows: dm-0: rw=0, want=31933816664, limit=4838391808 attempt to access beyond end of device dm-0: rw=0, want=32472792952, limit=4838391808 attempt to access beyond end of device dm-0: rw=0, want=33011769240, limit=4838391808 attempt to access beyond end of device dm-0: rw=0, want=33550745528, limit=4838391808 attempt to access beyond end of device dm-0: rw=0, want=34089721816, limit=4838391808
How do I access the files in question?
Any suggestions or enlightment would be greatly apreciated.
