Description rainer 2016-12-05 09:20:02 UTC

we send snapshots from a host with (old) SmartOS to a FreeBSD 10.1.

hw.machine: amd64
hw.model: Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz
hw.ncpu: 12
hw.byteorder: 1234
hw.physmem: 68558307328
hw.usermem: 15738359808
hw.pagesize: 4096
hw.floatingpoint: 1
hw.machine_arch: amd64
hw.realmem: 70866960384

This server was never really rebooted after it went into production, so upon reboot (bringing it to 10.1-RELEASE-p41, to update it to 10.3-RELEASE afterwards), it was discovered that it couldn't import its zpool anymore.

Lots and lots of
g_dev_taste: make_dev_p() failed (gp->name=zvol/storage/backup/ahostnamehere/some-guid-disk1@zfs-auto-snap:daily-2016-11-22-00:00, error=63)

It seems there is a 63 character limit in place here (judging from various post in mailing-lists).

I booted with the 11.0 install CD and tried to mount the zpool with that (LiveCD mode) - it showed the same error messages.

I'm updating it to 10.3 at the moment, for the sake of having it on a supported release.

Is there any fix for this?
We're not really in a position to rename the snapshots on the source-system.
