[OpenIndiana-discuss] Access to /etc on a pool from another system?

[Reginald Beardsley]

I would expect /mnt to contain /mnt/etc also.

rhb at openindiana:~# df /mnt
/                  (rpool/ROOT/oi_151 ):360070851 blocks 360070851 files
rhb at openindiana:~# 


There's nothing particularly odd about the /mnt/fpool.

This is the "zfs list" entry for /rpool

rpool                                  56.7G   172G  45.5K  /rpool

So w/ fpool mounted on /mnt instead of / everything is as normal.  The contents of /mnt/fpool are exactly what you find in /rpool


There were no errors that I recall other than fat fingers.

zfs treats / specially.  I ran into this last year about this time when trying to clone the same install of Solaris 10 u8 onto an HP z400 & a f700 laptop.  Finally gave up after almost 3 weeks.  There's probably a way to do it, but every way I found I encountered "you can't get there from here" which was a real surprise as I've always been able to do this w/ ufs.

Doing the obvious: 

boot from a USB drive image
create filesystem on target
copy filesystem contents fomr baseline

failed no matter what I tried.  zfs send, flar, tar & cpio.

Now that I think about it, the problems seemed to revolve around the special way that zfs and beadm treat /.

Just to be sure I just ran a scrub on fpool.

rhb at openindiana:~# zpool status fpool
  pool: fpool
 state: ONLINE
  scan: scrub repaired 0 in 0h9m with 0 errors on Tue Mar 20 05:08:56 2012
config:

	NAME        STATE     READ WRITE CKSUM
	fpool       ONLINE       0     0     0
	  c0t0d0s0  ONLINE       0     0     0

errors: No known data errors


I've imported and exported fpool quite a few times now w/o problems
