Subject: Defragmenting a RAID 5
volume?
Hello people,
We recently experienced a hang in our
database server, WIN2k Advanced server with raid 5 for Oracle 817 database
files.
Examining the perf logs showed
that Event 2022 caused the hang:
Event ID: 2022 Source: Srv Description: Server
was unable to find a free connection 144 times in the last
60 seconds.

After I examined the alert log, I saw an object trying
to extend but fails because the DBF ran out of space. This happened on the
time/instance that the server started to stop responding. The DBF is supposed
to extend because it is configured to AUTOEXTEND. The available disk space
isn't also supposed to constrain the DBF's extension of 64MB, free space of 9+
GB could still accomodate this, obviously. More importantly, this can happen
without crashing the server.
According to Microsoft's website (http://support.microsoft.com/default.aspx?scid=kb;en-us;245077), possible resolutions are to defragment the disk or
allocate more disk space. Disk space is not much of an issue because the
volume still has 9+ GB. My question is, can a RAID 5 volume be
defragmented? Is it sane, technically? The volume is 130GB in size...
Best regards,
Rhojel
