RHEL 3 on VMware chrashed, resulting in "directory contains a hole" messages

[Kenneth Holter]

Thanks for your reply.

In the Vmware VC console, I located the server in question, clicked "manage
snapshots", and clicked the snapshot and the hit the "delete" button.
Basically the same procedure I've done a thousand times before, only this
time it caused the linux server to crash. I've seen this a few times before,
actually, but haven't been able to find the reason why the linux server
crashes. It must be a bug within Vmware, or with Linux on Vmware, that's
causing it. Have anyone else experienced this before?

We were not able to rescue the server that crashed yesterday, so we decided
to migrate to a new RHEL 5 server which was allready a planned activity. But
I must say that I'm a bit worried about running linux on Vmware having had a
few (maybe four or five) servers crashing on me the past year and a half
I've been running RHEL on vmware. So if anyone knows how to debug these
issues to increase the stability I'd greatly appreciate it. Unfortunately, I
haven't got very much data to analyze, so I could use some advice on how to
retrieve such data the next time a linux server crashes.


Regards,
Kenneth
