Hi,
I've output of space allocation which I can't explain. I hope someone
can point me at the right direction.
The allocation of my "home" filesystem looks like this:
jo...@onix$ zfs list -o space p0/home
NAME AVAIL USED USEDSNAP USEDDS USEDREFRESERV USEDCHILD
p0/home 31.0G 156G 86.7G 69.7G 0 0
This tells me that *86,7G* is used by *snapshots* of this filesystem.
However, when I look at the space allocation of the snapshots, I don't
see the 86,7G back!
jo...@onix$ zfs list -t snapshot -o space | egrep 'NAME|^p0\/home'
NAME AVAIL USED USEDSNAP USEDDS USEDREFRESERV USEDCHILD
p0/h...@s1 - 62.7M - - - -
p0/h...@s2 - 53.1M - - - -
p0/h...@s3 - 34.1M - - - -
p0/h...@s4 - 277M - - - -
p0/h...@s5 - 2.21G - - - -
p0/h...@s6 - 175M - - - -
p0/h...@s7 - 46.1M - - - -
p0/h...@s8 - 47.6M - - - -
p0/h...@s9 - 43.0M - - - -
p0/h...@s10 - 64.1M - - - -
p0/h...@s11 - 563M - - - -
p0/h...@s12 - 76.6M - - - -
The sum of the USED column is only some 3,6G, so the question is "to
what is the 86,7G of USEDSNAP allocated?" Ghost snapshots?
This is with zpool version 22. This zpool was used a year or so in
onnv-129. I upgraded the host recently to build 151a but I didn't
upgrade the pool yet.
Any pointers are appreciated!
Joost
