Hello fellow admin,
As part of our backup policy, we wish to backup regularly the / (root) and
/usr partitions. However, we are experiencing problems mounting the backup
filesystem created with dump command. The backup devices do not appear to
have any filesystem present. In addition, the following error message
appears in the system log:
-- cut --
Oct 23 20:17:28 pol1 vmunix: I/O error (errno 30) for block(0x0, 0x0) on device 8,33792

Even 'fsck' reports problems. Obviously I am doing something wrong,
but "I can not see trees for the wood". Any help would be very
appreciated.
Summary to follow.
