Subject: [linux-lvm] metadata problems while testing lvm2 git with dm_thin_pool
Date: Fri, 27 Jul 2012 13:57:45 +0200 [thread overview]
Message-ID: <50128239.4030208@profihost.ag> (raw)
Hello list,
i'm testing dm_thin_pool with lvm2 right now. And i'm always running
into the situation that the metadata get's full.
Kernel: 3.5-rc7
lvm/dmeventd: up2date git version 186a2772
I created my thin disk like this:
lvcreate -L 10G -T thinvol/pool1 -V 100G --name disk1
After some autoresizing lvs looks like this:
# lvs
LV VG Attr LSize Pool Origin Data% Move Log Copy%
Convert
disk1 thinvol Vwi-a-tz 100,00g pool1 22,95
pool1 thinvol twi-a-tz 33,77g 67,97
# dmsetup table
thinvol-pool1: 0 70811648 linear 253:4 0
thinvol-disk1: 0 209715200 thin 253:4 1
thinvol-pool1-tpool: 0 70811648 thin-pool 253:2 253:3 128 0 0

thinvol-pool1_tdata: 20971520 49840128 linear 8:17 20998144

MYVOL-thin_pool2_tdata: 20971520 31227904 linear 8:129 20998144
