Hello all,
i set up a PC with FreeBSD 9.1-Release and 2 zfs pools.
One is a mirror from which FreeBSD is booting
(tough enough without getting "error 2"),
the other one a raidz2 for data.
The disks for the raidz2 are encrypted with geli and attached manually.
I noticed that a "zpool status" or a "zfs list" before attaching
the encrypted disks waits for about one minute before showing output.
When they finally do, the output is as expected, the raidz2 pool is shown as
UNAVAIL and its datasets are not listed.
When all the disks are attached with geli, the outputs are given
immediately.
On boot there are 2 delays.
One of about 1 minute after the output
"Setting hostid: 0x........"
and one of 2 minutes after
"Mounting local file systems:.".
Both these outputs don't show up in dmesg, which ends with
"Trying to mount root from zfs:zroot/ROOT []..." shortly before.
I suspect that the boot delays too are because of the encrypted pool.
A different machine running FreeBSD 8.3-RELEASE has a delay of only
about 3 seconds on "zpool status" with an encrypted pool
and also the boot shows no annoying anomalies.
Any idea how to get rid of these really long delays?
Regards,
Henner Heck
