> Dear ZFS experts,
somehow one of my zpools got corrupted. Symptom is that I cannot
import it any more. To me it is of lesser interest why that happened.
What is really challenging is the following.
Any effort to import the zpool hangs and is unkillable. E.g. if I
issue a "zpool import test2-app" the process hangs and cannot be
killed. As this originally happened on a Sun Cluster node, this
finally panic'ed the node, the storage resource failover to the other
node, hung again, panic'ed this node as well ..... Not a good scenario
for a production system.
I now have 2 questions:
1. Could the hang and the unkillable process be avoided by setting the
zpool's failmode to continue? It is currently set to "wait" which I
think is the default.
2. Is it true that I can only set the failmode property while the
zpool is imported? As trying to set it hangs and is unkillable.
If I do a "zpool import" the following shows up:
pool: test2-app
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
test2-app ONLINE 0 0 0
c1t1d7 ONLINE 0 0 0
errors: No known data errors
If I truss "zpool import test2-app" the last lines are:
open("/dev/dsk/c1t1d7s0", O_RDONLY) = 6
fstat(6, 0xFFBFB404) = 0
modctl(MODSIZEOF_DEVID, 0x01D80038, 0xFFBFB48C, 0x0008CC24,
0xFF21B480) = 0
modctl(MODGETDEVID, 0x01D80038, 0x0000001C, 0x000E9F90, 0xFF21B480) = 0
fstat(6, 0xFFBFB404) = 0
modctl(MODSIZEOF_MINORNAME, 0x01D80038, 0x00006000, 0xFFBFB48C,
0xFF21B480) = 0
modctl(MODGETMINORNAME, 0x01D80038, 0x00006000, 0x00000002,
0x000F1FC8) = 0
close(6) = 0
ioctl(3, ZFS_IOC_POOL_STATS, 0xFFBFA4F0) Err#2 ENOENT
ioctl(3, ZFS_IOC_POOL_TRYIMPORT, 0xFFBFA5C8) = 0
Thanks
