hi folks
I've been running my fileserver at home with linux for a couple of years and
last week I finally reinstalled it with solaris 10 u4.
I borrowed a bunch of disks from a friend, copied over all the files,
reinstalled my fileserver and copied the data back.
Everything went fine, but after a few days now, quite a lot of files got
corrupted.
here's the output:
# zpool status data
pool: data
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

Last night I found out about this, it told me there were errors in like 50
files.
So I scrubbed the whole pool and it found a lot more corrupted files.
The temporary system which I used to hold the data while I'm installing solaris
on my fileserver is running nv build 80 and no errors on there.
What could be the cause of these errors??
I don't see any hw errors on my disks..

although a lot of soft errors.
Linux said that one disk had gone bad, but I figured the sata cable was somehow
broken, so I replaced that before installing solaris. And solaris didn't and
doesn't see any actual hw errors on the disks, does it?
