I've a zfs pool named 'ppool' with two vdevs(files) file1, file2 in it.
zdb -l /pak/file1 output:
version=16
name='ppool'
state=0
txg=3080
pool_guid=14408718082181993222
hostid=8884850
hostname='solaris-b119-44'
top_guid=4867536591080553814
guid=4867536591080553814
vdev_tree
type='file'
id=0
guid=4867536591080553814
path='/pak/file1'
metaslab_array=23
metaslab_shift=19
ashift=9
asize=68681728
is_log=0
zdb -l /pak/file2 output:
version=16
name='ppool'
state=0
txg=3081
pool_guid=14408718082181993222
hostid=8884850
hostname='solaris-b119-44'
top_guid=4015976099930560107
guid=4015976099930560107
vdev_tree
type='file'
id=1
guid=4015976099930560107
path='/pak/file2'

bash-3.2# zdb -uuu ppool
Uberblock
magic = 0000000000bab10c
version = 16
txg = 3082
guid_sum = 4845486699483555527
I see that the uber block ub_guid_sum is not equal to the sum of guid's of both
the vdevs. Can someone please explain me why?
Regards,
pak
