Hello
I have an amd64 server running OpenSolaris 2009-06. In December I created one
container on this server named 'cpmail' with it's own zfs dataset and it's been
running ever since. Until earlier this evening when the server did a kernel
panic and rebooted. Now, I can't see any contents in the zfs dataset for this
zone!
The server has two disks which are root mirrored with ZFS:
# zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
mirror ONLINE 0 0 0
c8t0d0s0 ONLINE 0 0 0
c8t1d0s0 ONLINE 0 0 0
errors: No known data errors
Here are the datasets:
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 161G 67.6G 79.5K /rpool
rpool/ROOT 3.66G 67.6G 19K legacy

rpool/repo 6.56G 67.6G 6.56G /rpool/repo
rpool/swap 2.00G 69.4G 130M -
/zones/cpmail is where it should be mounting the zone's dataset, I believe.
Here's what happens when I try and start the zone:
# zoneadm -z cpmail boot
could not verify zfs dataset mailtmp: dataset does not exist
zoneadm: zone cpmail failed to verify
So the zone is trying to find a dataset 'mailtmp' and failing because it
doesn't exist. So, what happened to it?
Here's the zone config file, at /etc/zones/cpmail.xml (with IP address
obfuscated)
# cat /etc/zones/cpmail.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE zone PUBLIC "-//Sun Microsystems Inc//DTD Zones//EN"
"file:///usr/share/lib/xml/dtd/zonecfg.dtd.1">
<!--
DO NOT EDIT THIS FILE. Use zonecfg(1M) instead.
-->
<zone name="cpmail" zonepath="/zones/cpmail" autoboot="false" brand="ipkg">
<network address="xxx.xxx.xxx.xxx" physical="bge1"/>
<dataset name="mailtmp"/>
</zone>
I just don't understand where the dataset 'mailtmp' went to. Perhaps it was an
initial name I used for the dataset and I then renamed it to cpmail, but then I
can't see any of the zones files in /zones/cpmail :
# find /zones/cpmail/
/zones/cpmail/
/zones/cpmail/dev
/zones/cpmail/root
Does ZFS store a log file of all operations applied to it? It feels like
someone has gained access and run 'zfs destroy mailtmp' to me, but then again
it could just be my own ineptitude.
Thank you
Jesse
