Subject: [linux-lvm] Trouble creating snapshot device
Date: Mon, 29 May 2006 16:55:20 +0200 [thread overview]
Message-ID: <1148914520.6979.12.camel@earth.han.nl> (raw)
Hello,
We are in trouble creating snapshot devices on fedora-core 4... Kernel
version: 2.6.16-1.2111_FC4smp. We have created new RPM's using the
development SRPMS (device-mapper-1.02.07-1.0 & lvm2-2.02.06-1.2.1). The
same trouble occurs with stock device-mapper & lvm2 RPM's!
Sometimes the snapshot device is created succesfully but most times is
fails... The script:
ophelia.han.nl:~# lvs
LV VG Attr LSize Origin Snap% Move Log Copy%
cache vg -wi-ao 1.00G
home vg -wi-ao 500.00M
log vg -wi-ao 500.00M
postfix vg -wi-ao 10.00G
tmp vg -wi-ao 100.00M
usr vg -wi-ao 800.00M
var vg -wi-ao 200.00M
ophelia.han.nl:~# lvcreate -s -n test -L 100M /dev/vg/postfix
LV vg/test in use: not deactivating
Couldn't deactivate new snapshot.
ophelia.han.nl:~# lvs

Anyone any idea?
