Hi all,
I'm migrating to a new laptop from one which has had hardware issues lately. I
kept my home directory on zfs, so in theory it should be straightforward to
send/receive, but I've had issues. I've moved the disk out of the faulty
system, though I saw the same issue there.
The behavior I have is the zfs send will start and work up to a point (about
792MByte), but then all zfs activity with the source pool/filesystems will
hang. When I was doing it across the network, the sender would have all
zpool/zfs commands hang after hitting this point, and now that both disks are
on the same system, zpool/zfs commands having to do with the sending pool hang
once it gets to this point.
Is there anything I can do to recover from this condition? Near as I can tell,
I can mount the filesystem and access things, so I could try just a bulk copy,
but I'd like to know why this won't work. Is there any data I can gather which
may help identify the cause?
It seems that the zpool/zfs commands working with that pool shouldn't hang,
even if one zfs send/receive is hitting this condition.
I did some searches for bugs, but didn't find anything helpful.
