o Well sun-managers comes through again. I received 3 replies before I got
my own copy of the mail I sent.
o After a reformat my disk is back to life, judging from comments it's not
clear for how long but it is back. This incident has spurred new
interest in spare parts by management.
o I was able to get a full backup even though I was getting 'bread' errors
during dump (It took a real long time to do this).
o I was considering some repairing but 'rwolf@dretor.dciem.dnd.ca (Robert J
Wolf)' suggested against it and in fact there doesn't appear to have been
a need for it.
o Since the Reformat of the disk I haven't had any problems at all with the
drive. Some people suggested checking cabling. I was reasonably sure
that wasn't it as there are 4 disks on one controller and only 1 was
having problems. Had the cable been jarred (it was disk 0) I suspect the
errors would have propogated to the other drives as well.
o On a psychotic note. I upgraded to 4.1.1 since the system was down
anyway. I really ought to have my head examined for that decision.
o Another note to all sun managers out there. If you are currently using
Exabytes to do these nice big backups make sure you have your Exabyte
targeted where a Generic Sun Kernel can find it. This was a major pain
as I had to get enough of a system up to the point where I could build a
new kernel before I could even start reloading from my dump tapes. This
was part of my decision process for 4.1.1 upgrade as I had to load a lot
anyway even had I stayed 4.1. (The statement above still holds though).
o I think my plan will be to buy 1 hot spare ~$8000 with 5 year warranty
and have it around, then if one dies I can send it back to be rebuilt.
curt@ecn.purdue.edu (Curt Freeland) said: "When I sent my dead drive to
Seagate for repairs, they replaced the electronics, and HDA. I basically
got a new drive for the price of a $2k rebuild."
o Of course when I finally got my disk back up at 0430 the day after it
crashed (10 hours after I started the level 0 dump mentioned above) I had
Stale NFS File Handles all over the network (I think I still have some
residual effect from this). This caused extreme whining from my user
types.
:-) However having not shaved for the past 3 days and being sufficiently
:-) grumpy and tired makes people not want to talk to me anyway.
o On another note I noticed that now all my partitions on my id000 are <
0.2% fragmentation whereas some of my other drives are > 2.0%
fragmentation. Anyone have any thoughts on how often a level 0 dump,
reformat, reload, could be useful?
