[zfs-discuss] OS restore to first hard disk on ZFS while booted from second had disk

Hi, I have a Solaris 10 x86 server with 2 hard disks running on mirrored UFS configuration. Currently we are trying to implement a OS backup solution using Networker 7.6. I can successfully backup the OS to a remote Networker server. But now the trouble is if I need to perform a full Solaris

[zfs-discuss] ZFS/ARC consuming all memory on heavy reads (w/ dedup enabled)

Greetings Gentlemen, I'm currently testing a new setup for a ZFS based storage system with dedup enabled. The system is setup on OI 148, which seems quite stable w/ dedup enabled (compared to the OpenSolaris snv_136 build I used before). One issue I ran into, however, is quite baffling: With

[zfs-discuss] Recurring checksum errors on RAIDZ2 vdev

Hello all, I'm having a problem that I find difficult to diagnose. I have an IBM x3550 M3 running nexenta core platform 3.0.1 (134f) with 7x6 disk RAIDZ2 vdevs (see listing at bottom). Every day a disk fails with Too many checksum errors, is marked as degraded and rebuilt onto a hot spare. I've

[zfs-discuss] Question regarding incremental zfs send/recv for hundreds of zfs filesystems under one pool

There is only one pool and hundreds of zfs file systems under that pool. New file systems are getting created on the fly. Is it possible to automate zfs incremental send/recv in this scenario? My assumption is negative as incremental send/recv needs a full snapshot to be sent first before

Thanks Richard for the prompt response. But second time same commands creates dir3 too. I mean to say, as I said earlier, first time it gives the mounting error and does not create dir3 *# zfs create -p tank/dir1/dir2/dir3* *cannot mount '/tank/dir1/dir2': directory is not empty* *#* but if I

Re: [zfs-discuss] Question regarding incremental zfs send/recv for hundreds of zfs filesystems under one pool

Thanks Ian for your response. So you are saying, if I create recursive snapshot of the pool, it will be able to do the incremental send/recv for the file systems created on the fly? I was thinking that if the file systems are created on the fly, then there is no previous snapshot for the newly
