HelloI 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/ROOT/opensolaris 3.66G 67.6G 3.51G / rpool/cpmail 139G 67.6G 22K /zones/cpmail rpool/cpmail/ROOT 139G 67.6G 19K legacy rpool/cpmail/ROOT/zbe 139G 67.6G 139G legacy rpool/dump 2.00G 67.6G 2.00G - rpool/export 7.64G 67.6G 7.49G /export rpool/export/home 150M 67.6G 21K /export/home rpool/export/home/jesse 150M 67.6G 150M /export/home/jesse 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.
With the version of opensolaris that you're running, the zone's root dataset won't be mounted until the zone boots. You can see this in the 'zfs list' output above where the mountpoint is legacy and you can look at the zfs mounted property as well. Since the zone is configured with a dataset that doesn't exist, it can't boot so the zonepath dataset isn't mounted. You can use the 'zpool history' command to see what zfs operations were done. I don't know why the mailtmp dataset no longer exists. Jerry _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
