Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?

2008-11-09 Thread Alan Romeril
I had a problem like that on my laptop that also has an rge interface, ping 
worked fine, but ssh and ftp didn't.  To get around it I had to add
 set ip:dohwcksum = 0 
to /etc/system and reboot.

That worked and is worth a try for you :)

Cheers,
Alan

Since you are using the rge driver, you might be getting bit by CR6686415.
http://bugs.opensolaris.org/view_bug.do?bug_id=6686415

The symptoms are that some packets work, more likely with small packets
like pings, but large packets might not work.  I've also had trouble not 
being
able to talk to systems on my LAN, but able to get to the internet.   
Try the
workaround in the CR.

 Thanks for the replies, it seems like I may have to rewind a bit here and fix 
 some network issues on the solaris box before I can move forward with the OSX 
 connecting...

 As I mentioned, ping between boxes works fine. I can ping my osx box, my 
 router (192.168.1.1) and my other NAS.  But I last night I decided to have a 
 try with SMB since I wasn't getting far with NFS.  That's when I discovered 
 the Solaris box can't connect to the internet (needed to download some smb 
 packages, or are they on disk somewhere?).  Anyway I took the approach of 
 doing a clean install, since I've played around with so many things trying to 
 get NFS working.

 So after a clean install I noticed again that the dhcp had failed to assign 
 ipaddress to the interface.  So I started patching again things that seem to 
 be missing, the hostname.rge0 file was missing, so I added an entry with my 
 hostname (zfsnas).  I also had to tweak the hosts file and add 'dns' to 
 nsswitch.conf and create a file resolv.conf.  So here is my current setup:



 [EMAIL PROTECTED]:~# ifconfig -a
 lo0: flags=2001000849UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL mtu 8232 
 index 1
   inet 127.0.0.1 netmask ff00 
 rge0: flags=201000843UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS mtu 1500 index

   inet 192.168.1.122 netmask ff00 broadcast 192.168.1.255
   ether 0:1c:c0:8e:a:3d 
 lo0: flags=2002000849UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL mtu 8252 
 index 1
   inet6 ::1/128 

 [EMAIL PROTECTED]:~# cat /etc/hostname.rge0

 [EMAIL PROTECTED]:~# cat /etc/nwam/llp
 rge0  static  192.168.1.122

 [EMAIL PROTECTED]:~# netstat -rn

 Routing Table: IPv4
   Destination   Gateway   Flags  Ref Use Interface 
   - - -- -

 127.0.0.1127.0.0.1UH1294 lo0 

 But even with all this, I can't connect outside of my LAN.  Should I switch 
 from nwam to a manual configuration?  or should nwam be able to handle this.  
 It seems strange already the the dhcp default setup fails.  Anyway, I don't 
 need internet access from this box, I was just trying to workout how to 
 download and install SMB.  But it did make me wonder if this might be related 
 to routing issues that might also affect the NFS stuff...

 With regard to ZFS, I have a mirrored pool of two disks 'data' and I create a 
 fs as follows:

 [EMAIL PROTECTED]:~# zfs create -o casesensitivity=mixed data/backup
 [EMAIL PROTECTED]:~# zfs set sharenfs=on data/backup
 [EMAIL PROTECTED]:~# zfs set atime=off data

 Next I used system - administration - shared folders to add the /data/backup 
 directory for sharing with any computer in my LAN.  This seemed to work 
 previously, but now I'm noticing that since my fresh install nothing gets 
 remembered.  WHen I re-open the shares gui, the previous share is gone.  Any 
 tips on this one too?

 Sorry for so many questions, but I'm quite new to all this, but determined to 
 get things working now that I bought some specific hardware for the job.  
 Would it be worth trying with 2008-11 i noticed a 101a rc1b build that's now 
 available, or is it going to be too newbie unfriendly?

wow, well done peeps, that was the problem!  Request to re-number that bug to 
666.  Totally evil, and what a waste of time that has caused.  Anyway, I have 
internet access from the box, which allowed me to easily install SMB which 
after a bit of messing around has now allowed me to access the box from OSX via 
SMB :))

I re-tested the NFS, but that still failed, but to be honest, I'm happier with 
smb anyway since it allows my other machines easier access to the zfs pool.

thanks to all for the emails and postings here.

[zfs-discuss] Fully supported 12-port SATA cards?

2008-11-09 Thread Henrik Johansson
I am helping a friend who is build a storage server for his company  
and I have advocated for Solaris and ZFS.

But now we are having trouble to find  any good SATA controller for  
12+ disks, there are Areca cards, but they seems very flaky (24 port  
support, but hangs with more than 12 in JBOD mode, hangs on disk  
failures etc).

The AOC-SAT2-MV8,AOC-USAS-L8i  have been mentioned, but it had  
problems with device numbering and/or as I understood it no support  
for hot plugging.

Isn't  there any supported PCI.* SATA card with at least 12 ports that  
do work and have a real driver supporting hot plugging/cfgadm- 
operations?

The HCL does not tell you everything, and scanning the lists did not  
show any consensus regarding this. This seems to have been a problem  
for years, I tried to find a card for myself a while back.

[zfs-discuss] Is a manual zfs scrub neccessary?

2008-11-09 Thread Douglas Walker

Hi,

I'm running a 3Tb RAIDZ2 array and was wondering about the zfs scrub 
function.

This server runs as my backup server and receives an rsync every night.

I was wondering if I _need_ to explicitly run a zfs scrub on my zpool 
periodically.

There's a lot of info on google about running a scrub but not whether 
it's actually needed or under what circumstances you might run one  -  
so I thought I'd ask the list it's opinions on this.

If zfs does a background scrub continually anyways - is there any need 
to manually run a scrub?

I'd imagine a scrub of a 3Tb array would take quite a while (its 7200rpm 
SATA disks) and if I ran a scrub this would likely overlap with my 
nightly rsyncs causing yet more I/O. Wouldn't this stress the disks more?

If it is necessary - how often are people running a manually scrub? Once 
a week? month?


regards


D

Re: [zfs-discuss] Is a manual zfs scrub neccessary?

2008-11-09 Thread Nathan Kroenert
The big win for me in doing a periodic scrub is that in normal 
operation, ZFS only checks data as it's read back form the disks.

If you don't periodically scrub, errors that happen over time won't be 
caught until I next read that actual data, which might be inconvenient 
if it's a long time since the initial data was written.

As I have a lot of data that is pretty much only read once or twice 
after it's originally written, I could have stuff going bad over time 
that I don't know about.

Scrubbing makes sure there is a limit on the amount of time between each 
'surprise!'.

:)

I scrub once every month or so, depending on the system.

So, in direct answer to your question, No - You don't *need* to scrub. 
But - It's better if you do. ;)

My 2c.

Nathan.

2008-11-09 Thread Ross
Personally I'd buy Sun hardware, an x4240, or an x2200 with a J4200.  Other 
hardware does work, but as you've seen, there appear to be a lot of limitations 
at the moment.

It is a very wise idea to perform a periodic scrub of your pool.  This 
should substantially decrease the actual risk of data loss.

 If zfs does a background scrub continually anyways - is there any need
 to manually run a scrub?

Zfs does not do a background scrub.  It only verifies data as it is 
read, and performs corrections if there is a redundant good copy.

 If it is necessary - how often are people running a manually scrub? Once
 a week? month?

Hard drives don't wear out from being used.  I have cron jobs set up 
to scrub my drive array every night and on some USB backup drives, 
once a week.  The only impediments to scrubbing as often as possible 
is that scrubbing decreases the available disk access performance 
during the scrub and that taking snapshots resets the scrub from the 
beginning.  Of course there may be more power consumption during a 
scrub.
