I have development box with apache and userdir mod enabled.
Sometimes, entire /home partition becomes inaccessible. Apache can't access scripts stored there, and I cant cd to /home nor ls its content in any way.
Otherwise everything work ok. Apache works (when not accessing /home), db works, browsing other partitions works but /home is stuck.
Software RAID 5 is used.
I looked on every log I found, check raid with cat /proc/mdstat, all is good, no error nor anything suspicious.
I don't know where else to look or which diagnostic command to run.
Edit: it was running about 5 years without problem. These trouble starts today in the morning when server was turned on. No system update was done in past few days and no config or anything was changed. My guess is faulty hdd.
Any leads?
Box is runing Gentoo Linux 2.6.34-r2
