Drive in my solaris box that had the OS on it decided to kick the bucket this
evening, a joyous occasion for all, but luckly all my data is stored on a zpool
and the OS is nothing but a shell to serve it up on. One quick install later
and im back trying to import my pool, and things are not going well.
Once I have things where I want them, I issue an import
# zpool import
pool: ftp
id: 1752478903061397634
state: FAULTED
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
see: http://www.sun.com/msg/ZFS-8000-3C
config:
ftp FAULTED corrupted data
raidz1 DEGRADED
c1d0 ONLINE
c1d1 ONLINE
c4d0 UNAVAIL cannot open
Looks like c4d0 died as well, they were purchased at the same time but oh well.
zfs should still be able to recover because i have 2 working drives, and the
raidz1 says its degraded but not destroyed. But the pool itself reads as
faulted?
I issue a import, with force thinking the system is just being silly.
# zpool import -f ftp
cannot import 'ftp': I/O error
Odd. After looking on the threads here I see that when importing a drive the
label of a drive is rather important, so I go look at what zdb thinks the
labels for my drives are
first, the pool itself
# zdb -l ftp
--------------------------------------------
LABEL 0
--------------------------------------------
failed to read label 0
--------------------------------------------
LABEL 1
--------------------------------------------
failed to read label 1
--------------------------------------------
LABEL 2
--------------------------------------------
failed to read label 2
--------------------------------------------
LABEL 3
--------------------------------------------
failed to read label 3
thats not good, how about the drives?

mmm, dead drive.
And so I have come to the end of my knowledge, I have no clue how to interpret
this information into exactly what went wrong, so I was hoping someone else
would be able to. Any help that anyone could provide would be just great. If
any other commands for data are needed, just ask.
