I have some major problems with a SCSI disk on the SUN SparcStation I. My knowledge of disks,partitions etc. is poor but in any case the problem follows. The system on boot produces two diagnostic messages. The first one is Cannot open: /dev/sd1h (Device or Address not found) Giving up on: /home This where the /home is mounted. I have basically lost the /home partition and about 35Mbytes of stuff that was not backed up ( At least a good fraction of it was not ). I used format-partition to print the label and it does not show anything allocated to "h". Any diagnostics ?? I also tried to mount the /dev/sd1a on /home and it works ok. The description of the problem is sketchy at best but I could provide more details to anyone who could HELP. The disk does not seem to be at fault because /dev/sd1a is mounted on /var and it seems to be ok. A different problem occurs here. When I do a "du" on /var the system prints panic: ..... and reboots. The second problem is CANNOT READ BLOCK: 201824 and this corresponds to /dev/sd1a. The SUN manual says: "This should not happen, talk to a guru if it does". The two problems seems to be related. I ran the whole gamut of non-destructive tests from format-analyze. No problems. I tried the backup command thinking the primary label went bad. No luck!! I also tried fsck. Does not recognize the device /dev/sd1h. fsck on /dev/sd1a gives be the CANNOT READ BLOCK message. I tried mounting /dev/sd1c which is the entire disk. The mount succeeds but I can see only the /var directory. This is where I ran out of ideas. I would be grateful for any ideas regarding this problem.
