I am having an issue where the Pool deactivates about every 5 to 10 days
with an I/O error and of course shows pool intergrity has been compromised.
This first started when the pool had ran completely out of available drive
space. The pool was deleted and then recreated and only the Groupwise Post
Office now resides on the volume. It is running on Netware 6.5 sp5 and has
had both the NSS5B and the Server.exe patches applied I have also upgraded
the firmware on both the raid controller and the drives and loaded new
drivers for the controller and raid. After this happens I have to run a
pool rebuild and then a verify and put it back online each time loosing
about 6mb to 10mb of data.
The exact error is as follows: POOL XXXXX/XXXXX is being deactivated
An I/O error (20204(zio.c[2260])) at block 18568266(file block 65446 )
(ZID 3) has compromised pool integrity.
I am thinking it may be a hardware issue but can't find any problems or
warning lights on the devices. I have found that this happens most of the
time between 2:00 a.m. to 3:30 a.m. in the morning. I would appreciate any
help in resolving this issue.
