Package: cryptsetup
Version: 2:1.0.6-7
Severity: normal
My setup has "/" on a normal primary partition, "/var" and "/usr" on
logical volumes, "/home" and "swap" on encrypted logical volumes.
"insserv" is also used to populate the runlevel directories
"/etc/rc*.d/", for parallel "startpar" execution of init scripts.
Following the "INIT INFO" section of the sysV init script
"/etc/init.d/cryptdisks-early" provided by this package, the "insserv"
program is creating links with the following execution order in
"/etc/rc0.d" and "/etc/rc6.d" (shutdown and reboot):
[...]
K01cryptdisks
[...]
K02cryptdisks-early
[...]
K10umountfs
K11lvm2
K12umountroot
K13halt
This leads to the following error when halting or rebooting:
Stopping early crypto disks...vg1-lv1_enc (busy)...\
vg1-lv4_enc (busy)...done.
[...]
Shutting down LVM Volume Groups Can't deactivate volume\
group "vg1" with 2 open logical volume(s)
failed!
[...]
Will now halt.
This happens because it is not possible to execute the "luksClose"
command on a volume containing a mounted filesystem or active swap.
When "cryptdisks-early" is started many filesystems are still mounted.
Subsequently also the "lvm2" script has problems to shut down the VG
because the mappings from cryptsetup are still existing.
I manually changed the links to have the following order:
[...]
K10umountfs
K11cryptdisks-early
K12lvm2
K13umountroot
K14halt
and then, after the change, it seems no error is affecting the "halt"
procedure any longer:
Will now deactivate swap:[...]
.
Will now umount local filesystems:[...]
.
Stopping early crypto disks...vg1-lv1_enc (stopping)\
...vg1-lv4_enc (stopping)... done.
Shutting down LVM Volume Groups 0 logical volume(s) in\
volume group "vg1" now active
Mounting root filesystem readonly...done.
Will now halt.
Proposed solution:
If no other implications prevent it, then changing the ordering of those
init scripts solves this bug: the only necessary step is to modify the
"INIT INFO" section in the "cryptdisks-early" script so that, in
runlevels 0 and 6, it runs after "umountfs".
