Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
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 -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
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. -- richard Peter Bridge wrote: 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 2 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 zfsnas [EMAIL PROTECTED]:~# cat /etc/hosts 127.0.0.1 localhost 192.168.1.122 zfsnas zfsnas.local loghost [EMAIL PROTECTED]:~# cat /etc/nodename zfsnas [EMAIL PROTECTED]:~# cat /etc/defaultrouter 192.168.1.1 [EMAIL PROTECTED]:~# cat /etc/nsswitch.conf ... hosts: files dns ...

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? ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
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?
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?
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 -- Douglas Walker Systems Administrator Jones Coulter Young Architects 321 Murray St, Perth WA, 6000 ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Is a manual zfs scrub neccessary?
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.

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. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

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.
