zfs discuss - Feb 2009 - Migrating to casesensitivity=mixed

Hi folks,

I know it''s not possible to change a pool to mixed sensitivity mode,
but does anybody know if it''s possible to do a send/receive from a pool
with this set to off, to one where it''s set to mixed?

thanks,

Ross

Thanks for reminding me.  Since I''m going to have to recreate my data
pool
(and restore from backups), I should deal with this at the same time.  If
I can.  I''ll watch for answers to your actual question here, and if
necessary conduct a small-scale test of my own and report back.

Well, after a quick test today I can confirm that this isn''t possible.

You can do a send/receive to an existing filesystem, but you need to use the -F
option, and it overwrites the receiving filesystem, giving it identical
properties to the source.

Looks like this''ll have to be a proper backup / restore job between
separate filesystems.

I know this problem has been mentioned a while back, but I haven?t seen or found
any usable solution. Sorry to bring it up again, especially if there IS a
solution.

Problem:

I have two servers: zeek and zed (both running nexenta flavor of Solaris x86).
On zed I created a zpool using two SATA drives and exported them via iscsi.
On zeek I created a zpool consisting of one local SATA drive + the iscsi
partition from zed with the following command:
 # zpool create hybrid c0t5d0 c2t010000E0815E35D500002A0049313F80d0
the latter being the iscsi partition. It?s created fine, works fine,
everything?s dandy... however:

To test for fault tolerance, I downed the nic on zed (ifconfig bge0 down), and
rebooted zeek. I was hoping that zeek would just alert me to zed not being
available and finish booting. But no. Zeek just keeps on spitting out the
following NOTICE messages:

Notice: one or more i/o devices have been retired
---
Notice: iscsi connection failed to set socket option TCP_NODELAY, SO_RCVBUF or
SO_SNDBUF
NOTICE: iscis connection(4) unable to connect to target SENDTARGETS_DISCOVERY
NOTICE: iscsi discovery failure - SendTargets (192.168.001.102)
---
over and over and over...

until I up the nic card on (ifconfig bge0 up)

Is there a way configure either ZFS or Solaris to ignore the pool called hybrid
if zed cannot be reached, or time out after x number of trying to reach zed, or
even mount just the local SATA disk only, or whatever it takes to simply booting
up?

Can?t believe the smart people behind ZFS overlooked this small detail.

S.
