Good link - thanks. I'm looking at the details for that one and learning a
little zdb at the same time. I've got a situation perhaps a little different in
that I _do_ have a current copy of the slog in a file with what appears to be
current data.
However, I don't see how to attach the slog file to an offline zpool - I have
both a dd backup of the ramdisk slog from midnight as well as the current file
based slog :
zdb -l /root/slog.tmp
version=14
name='siovale'
state=1
txg=4499446
pool_guid=13808783103733022257
hostid=4834000
hostname='shemhazai'
top_guid=6374488381605474740
guid=6374488381605474740
is_log=1
vdev_tree
type='file'
id=1
guid=6374488381605474740
path='/root/slog.tmp'
metaslab_array=230
metaslab_shift=21
ashift=9
asize=938999808
is_log=1
DTL=51
Is there any way that I can attach this slog to the zpool while it's offline?
