I guess what Steve meant was Solaris 'ODS' software RAID. Nothing to do with
an external RAID controller where the system simply sees as a big disk.
We use IBM RAIDs here, and of course we use Transarc's fsck (well,
v3fshelper).
What's interesting under Solaris is the possibility to just take a few disks
and let the system define a RAID set on them. Since ODS has its own fsck, I
wonder what happens if that one's replaced in turn by Transarc's fsck. A lot
of smoke if you're sceptical...
BTW, Steve: there is a way to force Transarc's fsck *not* to fsck the logged
file systems: I simply replaced the /dev/md/rdsk/dXX entries in /etc/vfstab
by '-'. That way the meta-devices are not fsck'ed, the 'sync' done somewhere
in /etc/init.d/SUNWmd.sync upon startup replays the log if all goes well and
the file systems are 'clean' anyway. My worries are more whether this sort of
magic is valid in all circumstances...
Cheers, Rainer
