hey all,
so i'm trying to mirror the contents of one zpool to another
using zfs send / recieve while maintaining all snapshots and clones.
essentially i'm taking a recursive snapshot. them i'm mirroring
the oldest snapshots first and working my way forward. to deal
with clones i have a hack that uses zfs promote. i've scripted it
and things seem to work... except of course for one thing. ;)
there's one snapshot on my system that i can't seem to transfer.
here's the problem:
---8<---
[EMAIL PROTECTED] zfs send export/ws/[EMAIL PROTECTED] | zfs receive -v -d
export2
receiving full stream of export/ws/[EMAIL PROTECTED] into export2/ws/[EMAIL
PROTECTED]
received 134MB stream in 28 seconds (4.77MB/sec)
[EMAIL PROTECTED]
[EMAIL PROTECTED] zfs send -i 070221 export/ws/[EMAIL PROTECTED] | zfs receive
-v -d export2
receiving incremental stream of export/ws/[EMAIL PROTECTED] into
export2/ws/[EMAIL PROTECTED]
cannot receive: destination has been modified since most recent snapshot
---8<---
as far as i know, there's nothing special about these two snapshots.
---8<---
[EMAIL PROTECTED] zfs list | grep export/ws/xen-1
export/ws/xen-1 105M 3.09G 104M /export/ws/xen-1
export/ws/[EMAIL PROTECTED] 570K - 103M -
export/ws/[EMAIL PROTECTED] 0 - 104M -
[EMAIL PROTECTED] zfs get -Hp -o value creation export/ws/[EMAIL PROTECTED]
1172088367
[EMAIL PROTECTED] zfs get -Hp -o value creation export/ws/[EMAIL PROTECTED]
1192301172
---8<---
any idea what might be wrong here? it seems that the problem is
on the recieve side. i've even tried doing:
zfs rollback export2/ws/[EMAIL PROTECTED]
before doing the second send but that didn't make any difference.
i'm currently running snv_74. both pool are currently at zfs v8,
but the source pool has seen lots of zfs and live upgrades.
