Glaring Bug

Post by fumoboy007 » Fri May 17, 2013 8:56 pm

1. Create a mirrored pool with 3 Seagate Backup Plus 4TB drives.
2. Verify that the pool is there using zpool list.
3. Unmount the ZFS disk using either Disk Utility or Finder.
4. Verify that the pool is there using zpool list. Notice that no pools are shown.
5. Try to mount the ZFS disk using Disk Utility. Notice that the ZFS disk disappears and a "disk was not ejected properly" alert pops up. The ZFS disk then reappears but it's still not mounted.
6. Verify that the pool is there using zpool list. Notice that no pools are shown.
7. Reboot.
8. Everything works again.

Note: Using the latest version 1.1.1

If I unmount, unplug, and plug back in, I get a panic after a few seconds. This is similar to other posts I saw from September/October 2012. Perhaps the above is the key to figuring all of this out.

Code: Select all

Workaround, and link to the earlier topic

Welcome to the forum!

Workaround

For the step above, instead of using Finder or Disk Utility:

  • zpool export nameofpool

Previously posted

Finder eject, reconnect, panic, type 14=page fault, zpool

Thanks for the workaround! I do hope this will be fixed in the future though. =S

Incidentally: what's the Mac, what's the pool configuration (zpool status) and how are the three disks connected? Any hub?

Mac Model Identifier: MacBookAir4,2
Pool Configuration: 3 disk mirror
Disk Connection: The drives are connected to a SIIG 4-port USB 3.0 hub (JU-H40512-S2) and the hub is connected to my MacBook Air's USB 2.0 port.

How does a hub affect things though?

USB 2.0 port

Post by grahamperrin » Sun May 19, 2013 6:17 pm

I wonder whether the bug would bite the same pool if instead, each disk had a separate host controller.
