I didn't know if I should post this to questions or stable but here it
is...
We had a power outage and now /home won't mount. Before the power outage
all was fine.
On boot I get the following...
.

.
Starting file system checks:
/dev/da0s1a: FILE SYSTEM CLEAN; SKIPPING CHECKS
/dev/da0s1a: clean, 41075 free (587 frags, 5061 blocks, 0.8%
fragmentation)

/dev/ad1s1e: DEFER FOR BACKGROUND CHECKING
/dev/da0s1d: DEFER FOR BACKGROUND CHECKING
/dev/ad1s1d: DEFER FOR BACKGROUND CHECKING

#
At this point all partitions are mounted except /home
I get the following errors when running fsck
# fsck /home
** /dev/ad1s1f
** Last Mounted on /home
** Phase 1 - Check Blocks and Sizes
INCORRECT BLOCK COUNT I=6 (37920 should be 0)
CORRECT? [yn] y

UNEXPECTED SOFT UPDATE INCONSISTENCY

ad1: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE>

THE FOLLOWING DISK SECTORS COULD NOT BE READ: 54947584, 54947606,
fsck_ufs: cannot alloc 3087484824 bytes for inoinfo
There are two drives on this system (da0 and ad1). There are two other
partitions on ad1 that mount with no problems and all partitions on da0
mount with no problems.
As root I've tried to run sysinstall and the disk label editor to try to
re-label the partitions on ad1 but when I select W, I get an error saying
it can't write to ad1.
Am I S-O-L or can I recover /home from this? If so, how?
The system is running 5.3-RELEASE-p18
Thanks
