Another kernel oops

— Morten @ 12:37

I believe it is time to get rid of ReiserFS on the server. It seems that all of the recent crashes have been in the reiserfs_clear_inode method, and it’s the only hint I’m able to extract from the kernel dumps as to what could be wrong. ReiserFS used to be very fast and rock stable (even on 64-bit), so I’m surprised it has devolved again. However, now that Hans Reiser looks set to spend 20 years behind bars (for the alleged murder of his wife), one might as well smell the coffee and move to a more reliable alternative.

So, the server was offline for roughly 7 hours this time. Clearly not the stability one was used to from Linux :-(
