[zfs-discuss] GUI to set ACLs

[Achim Wolpers]

Hi all!

I'm searching for a GUI tool to set ZFS (NFSv4) ACLs. I found some nautilus add 
ons in the web but they don't seen to work with nautilus shipped with OI. Any 
solution?

[zfs-discuss] RAM failure led to data corruption

[Achim Wolpers]

Hi!

Today I encountered data corruption on two zfs pools due to a RAM failure in my 
OI box running on a dell T710. My rpool now looks like this (after reboot):

  pool: rpool
 state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
entire pool from backup.
   see: http://www.sun.com/msg/ZFS-8000-8A
  scan: scrub repaired 0 in 1h1m with 1 errors on Tue Jan 31 19:59:50 2012
config:

NAME STATE READ WRITE CKSUM
rpoolONLINE   0 0 1
  mirror-0   ONLINE   0 0 2
c4t50014EE10313DE5Dd0s0  ONLINE   0 0 2

/rpool/service/svn/privat/db/revs/0/835
/rpool/service/svn/privat/db/revs/0/364

I have 17 files that are permanently corrupted. The corruption of gdm/core was 
found while scrubbing the pool. All the other 16 files where displayed as 
corrupted after the pool fell in degraded state. I'm not sure if these files 
are really corrupted, though: I can access all these files and  e.g. 
/usr/gnu/bin/rm works with no faults. All files have the identical md5 sum 
compared the the corresponding files of a different box, also running the same 
version of OI.

How do I find out, if these files are corrupted? If they appear to be ok, how 
do I get rid of the errors?

How can two healthy pools get that messed up, when a RAM DIMM gets broken?

[zfs-discuss] Replace block devices to increase pool size

[Achim Wolpers]

Hi!

I have a zpool biult up from two vdrives (one mirror and one raidz). The
raidz is built up from 4x1TB HDs. When I successively replace each 1TB
drive with a 2TB drive will the capacity of the raidz double after the
last block device is replaced?

[zfs-discuss] zfs + charset

[Achim Wolpers]

Hi!

I have a problem with the charset in the following scenario:

- OSOL Server with zfs pool und NFS/CIFS shares enabled
- OSX Client with CIFS mounts
- OSX Client with NFSv3 mounts

If one of the clients saves a file with a special character in the
filename like 'äüöß', the other client can not access that file. The
characters a displayed correctly on both clients as well as on the
server. What is the reason of this incompatibility of CIFS and NFS
invoked filenames and how can I get around it?

 What are the normalization properties of these filesystems? The zfs man page 
 says they're used when comparing filenames:
The normalization properties are set to none. Is this the key to my
solution?
