disk activity lights for the drives where /new-directory lives are still

accessing its disks (there's not much else running) so it seems like the
cp processes are still running.
Hmm, and you are sure that both disksets are OK and don't have any bad
sectors? What filesystems are you using?
At this point I don't see any alternative to
rebooting but I thought I'd
ask first to see if anybody had any other ideas on ways to gather
Difficult if you cannot access it anymore. I'm normally logging to a remote
machine so I can always see syslog output.
These symptoms have occurred once before. When I
rebooted that time, the
system came up without one of the data disks - the system said the
interface wasn't responding. But when I unplugged the disk and plugged
it back in and rebooted, it came back. There was actually a lot else
happened at that time, so I can't be sure it was as simple as it sounds.
I'll see if the same happens this time. I wasn't able to spot anything
useful in the logs and smart said the disk was OK, AFAICT.
Is that a RAID? We sometimes have trouble with bad connections, but that is
mostly due to very low humidity in our environment. I often need to re-seat
PCI cards etc because they vanish.
The new data directory is in an ext4 filesystem in an
LVM volume on an
mdadm RAID10 all on openSUSE 11.2 so another possibility is some kind of
problem in one of those systems. The drive is in a SATA hot swap cage
connected to a port on the motherboard; it's a WD RE4 1.5 TB.
Ah, there it goes. Hmm, running out of resources? If the new disks are still
flashing they are still writing, so the buffer might be over-full and
everything else is swapped out?
Could of course also be a network card problem....
Out of ideas now
