Files missing and corrupt.

Hi,
We are running SCO Unix 6.0 on a RAID 5 (3 hard drives). We run Medical Manger on our unix server. From the past 3-4 weeks, we are having issues with medical manager such as files missing, and recently today a file with around 300 MB data is all lost and we have 0 MB file. We had to restore the original file from backup.

I thought its a problem with RAID controller and talked to HP. They did the diagnosis and confirmed that the RAID is error free.
Now I think there is some problem with unix file structures or something like that..Could someone throw some light on this issue.
Any help is greatly appreciated.

Thanks.
A.

Hi,

some questions:
a) Is the RAID being handled with a hrdware RAID controller -- or in software?
b) What filesystem type do you have on the RAID? Is there only a single filesystem on the RAID device(s)?
c) When did you last reboot the system?
d) Can you post the /etc/fstab file contents and output from "mount", please?

Cheers,
JustUNIX

Hi JustUNix,

a) Is the RAID being handled with a hrdware RAID controller -- or in software?
I think its a heardware RAID controller, but I am not sure. Could you please let me know how to check this. I can contact HP to get this info.
b) What filesystem type do you have on the RAID? Is there only a single filesystem on the RAID device(s)?
 We only have SCO UNIX on this server.
c) When did you last reboot the system?
 3 days back
d) Can you post the /etc/fstab file contents and output from "mount", please?
There is no directory fstab under etc directory. Could it be with someother name under Unix ?

Thanks.

a) When there is some RAID options being displayed and/or tested, you have hardware RAID. Also, when you have an adapter card with several (usually more than two) connectores to attach to disk drives.
b) What does a
      # df
    or
      # df -k
   display? (Of course, without the #)
c) That's fine.
d) /etc/fstab: It's a file, not a directory. It may also be called /etc/vfstab
    What does the command
     # mount
    display

We did a check on the file system and found some errors. Probably this fixed the issue.

                /etc/fsck -ofull <Enter>
                /tcb/bin/integrity -em > /tmp/integ.rpt <Enter>
                /etc/tcbck <Enter>
                /tcb/bin/authck -a -v <Enter>
                /etc/fixmog -v <Enter>

I am going to give points to justunix.
