ADVFS Panic

[LucianoCarvalho]

Hi!

I'm receiving an error message on file /var/adm/messages about a domain:



AdvFS Domain Panic; Domain xx_domain Id 0x3e24be2a.0001921b
Sep 20 22:07:39 xxxxxx vmunix: An AdvFS domain panic has occurred due to either a metadata write error or an internal inconsistency. This domain is being rendered inaccessible.

What should I do abut it? At the moment the domain is mounted and working well. It's a Tru64 version 5.1A
Thanks in advance

First check the binary.errlog if hardware errors will be logged (dia -R).
If it is not a hardware error use verify to check the domain and correct any inconsistency.
Otherwise swap drive and restore filesystem from backup

Hi,
I second Ralph remarks.
1) Check the HW with DecEvent (dia) or Compa Analyze (ca). Look for disk errors.
2) If no HW problems are seen
a) If possible, take a full backup
b) If you have a succesful "tested" backup, You have 3 options.
you can try to solve this issue with the verify command.
or
you can run the fixfdmn utility and try to make your filedomain consistent again. (This command exist since v5.1A)
or
you remove your filedomain#filesets with rmfset/rmfdmn and create them again with mkfdmn/mkfset. This can be on new or on he same storage (This depends how you trust the current disks on which the current filedomain are located)

Good Luck
