I'm not on site yet but I'll check the kernel message.
Remotely it's acting the same as the first time. Oddly ping and nmap looks OK but nothing responds.
I'll be taking it off line until I can figure it out.
Any suggestions?
Is it possible to stop the resync to to get some data off it? It's really unresponsive with it running.
My guess is there is something wrong with a drive and with the raid resync code.
I'll do some tests on the drives. The rest I'll need help with.

Was running just fine for a few months.
System is very unresponsive. Sometimes takes a minute to respond to cat /proc/mdstat
I know some of this is because it's doing it's normal programs but it was not that much better in single user mode.
Much to my amazement it managed to do the overnight backups while resyncing.
Interested why it takes so long and if there is anything one can do?
As i recall it took about 120 minutes to build initially.
Other related issue:
Tried to resync on the sarge 2.6.8 kernel it seemed to go a little bit faster but it ended up kernel panicing at about 30%. Did this twice. Now I'm on the 2.6.10 and getting close to that point . Will know if it makes it past that soon.
I did get a smart message this morning but it not clear to me that there is anything wrong.
Here is the email:
