Mac frozen after rollback where there were children

Post by grahamperrin » Sat Oct 05, 2013 2:52 am

Spun off and condensed from viewtopic.php?p=5415#p5415

An export, and wondering about recovery (option -n to not perform the recovery):

Code: Select all
gpes3e-gjp4:~ gjp22$ date
Fri  4 Oct 2013 02:48:44 BST
gpes3e-gjp4:~ gjp22$ zpool export tall
gpes3e-gjp4:~ gjp22$ sudo zpool import -FnX tall
Password:
Would be able to return tall to its state as of Fri  4 Oct 02:49:01 2013.
gpes3e-gjp4:~ gjp22$ 


Rollback of the filesystem named 'tall' at the root of that pool:

Code: Select all
gpes3e-gjp4:~ gjp22$ date
Fri  4 Oct 2013 02:58:31 BST
gpes3e-gjp4:~ gjp22$ zfs rollback tall@2013-09-27-081037
cannot rollback to 'tall@2013-09-27-081037': more recent snapshots exist
use '-r' to force deletion of the following snapshots:
tall@2013-09-29-190323
tall@2013-09-29-200319
gpes3e-gjp4:~ gjp22$ zfs rollback -r tall@2013-09-27-081037
gpes3e-gjp4:~ gjp22$


Later:

Code: Select all
gpes3e-gjp4:~ gjp22$ zfs mount
gjp22/casesensitive             /Volumes/casesensitive
gjp22                           /Volumes/gjp22
gjp22/opt                       /opt
tall                            /Volumes/tall
tall                            /Volumes/tall/com.apple.backupd
tall                            /Volumes/tall/com.bombich.ccc


– to me, those three lines for 'tall' look wrong.

A bug with ZEVO Community Edition 1.1.1?

When I used option -n with zpool import, was the pool imported? I wonder.

Later still

A freeze of the Mac. For me this is extraordinary; I reported nothing like this whilst seed testing OS X 10.8.5 …

… so I was unsurprised to find that Bluetooth could not be found following a forced shut down (compare with Bluetooth-related comments in the 10.8.5 topic). Workaround for the bug affecting Bluetooth: shut down normally, just once.

All subsequent uses of the file system and its children have been problem-free. For example:

Code: Select all
gpes3e-gjp4:~ gjp22$ zfs mount | grep tall
tall                            /Volumes/tall
tall/com.apple.backupd          /Volumes/tall/com.apple.backupd
tall/com.bombich.ccc            /Volumes/tall/com.bombich.ccc
gpes3e-gjp4:~ gjp22$ date

gpes3e-gjp4:~ gjp22$ sw_vers

BuildVersion:   12F45
gpes3e-gjp4:~ gjp22$


Code: Select all
config:

   NAME                                         STATE     READ WRITE CKSUM
   tall                                         ONLINE       0     0     0

     GPTE_99056308-F5E2-4314-852C-4DA04732A2D0  ONLINE       0     0     0  at disk8s2


Side note

The USB 2.0 hub that's dedicated to those two disks is now in a preferred place: the rearmost port of the MacBookPro5,2.
