[zfs-discuss] How to get nfs work with zfs?
I am going to share a dir and it's subdir through NFS to Virtual Host, which include XEN(CentOS/netbsd) and ESXi，but failed, the following step is what I did: solaris 11: zfs create tank/iso zfs create tank/iso/linux zfs create tank/iso/windows share -F nfs -o rw,nosuid,root=VM-host1:VM-host2 /tank/iso chmod -R 777 /tank/iso centos: mkdir /home/iso mount -t nfs -o rw,nosuid solaris11:/tank/iso /home/iso echo newfile /home/iso/newfile.txt success echo newfile /home/iso/linux/newfile.txt failed，and display: permission denied and the, check the dir on solaris11: ls -al /tank/iso drwxrwxrwx 5 root root 8 Dec 5 13:04 . drwxr-xr-x 4 root root 4 Dec 2 22:45 .. drwxrwxrwx 2 root root 2 Dec 2 16:54 bsd drwxrwxrwx 2 root root 2 Dec 2 16:54 linux -rw-r--r-- 1 nobody nobody 8 Dec 5 12:57 newfile.txt drwxrwxrwx 2 root root 2 Dec 2 16:54 windows check the dir on CentOS: ls -al /home/iso drwxr-xr-x+ 2 root root 2 Dec 2 16:54 bsd drwxr-xr-x+ 2 root root 2 Dec 2 16:54 linux -rw-r--r--+ 1 nfsnobody nfsnobody 8 Dec 5 12:57 newfile.txt drwxr-xr-x+ 2 root root 2 Dec 2 16:54 windows I got couple questions: 1、why the owner of newfile.txt is nfsnobody on CentOS, and on solaris, it's nobody? 2、why the subdir do not have write access, how to accomplish it; 3、what does + mean? 4、do I need to remount a share dir after changing the file access on solaris(NFS server)？ ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Not totally true. By default, if you partition the disks, then the disk write cache gets disabled. But it's trivial to simply force enable it thus solving the problem. Granted - I just didn't want to get into a long story. With a self-described 'newbie' building a storage server I felt the best advice is to keep as simple as possible without adding steps (and without adding exposition about cache on partitioned disks - but now that you brought it up, yes, he can certainly do that). Besides, there's always a way to fill up the 1TB disks :-) Besides the OS image, it could also store gold images for the guest virtual machines, maintained separately from the operational images. how big of the solaris os'partition do you suggest? regards, Jeff -- *Jeff Savit* | Principal Sales Consultant Phone: 602.824.6275 | Email: jeff.sa...@oracle.com | Blog: http://blogs.oracle.com/jsavit Oracle North America Commercial Hardware Operating Environments Infrastructure S/W Pillar 2355 E Camelback Rd | Phoenix, AZ 85016 ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It gets confused when you have lots of filesystems, clones and zones.

I'm running 11 Express now, upgrading to Solaris 11 this weekend. Unless you have good reason to use Solaris 10, use Solaris 11 or OpenIndiana. I was once consider Openindiana, but it's still on development stage, I don't know if this version(oi_151a) is stable enough for production usage -- Ian. __**_ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/**mailman/listinfo/zfs-discusshttp://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] how to set up solaris os and cache within one SSD
hi, all I am a newbie on ZFS, recently, my company is planning to build a entry-level enterpirse storage server. here is the hardware list: 1 * XEON 5606 1 * supermirco X8DT3-LN4F 6 * 4G RECC RAM 22 * WD RE3 1T harddisk 4 * intel 320 (160G) SSD 1 * supermicro 846E1-900B chassis this storage is going to serve: 1、100+ VMware and xen guest 2、backup storage my original plan is: 1、create a mirror root within a pair of SSD, then partition one the them for cache (L2ARC), Is this reasonable? 2、the other pair of SSD will be used for ZIL 3、I haven't got a clear scheme for the 22 WD disks. any suggestion? especially how to get No 1 step done? ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Why would you want your root pool to be on the SSD? Do you expect an extremely high I/O rate for the OS disks? Also, not a good idea for performance to partition the disks as you suggest. because the solaris os occuppied the whole 1TB disk is a waste and the RAM is only 24G, does this could handle such big cache（160G）? 2、the other pair of SSD will be used for ZIL How about using 1 pair of SSD for ZIL, and the other pair of SSD for L2ARC 3、I haven't got a clear scheme for the 22 WD disks. I suggest a mirrored pool on the WD disks for a root ZFS pool, and the other 20 disks for a data pool (quite possibly also a mirror) that also incorporates the 4 SSD, using 2 each for ZIL and L2ARC. If you want to isolate different groups of virtual disks then you could have other possibilities. Maybe split the 20 disks between guest virtual disks and a backup pool. Lots of possibilities. hmm, could you give me an example and more details info suppose after mirror 20 hard disk, we got a 10TB usage space, and 6TB will be use for Vguest, 4TB will be use for backup purpose. within 6TB space，3TB might throught iSCSI to XEN domU, the other 3TB might throught NFS to VMware guest. 4TB might throught NFS for backup. thanks in advanced. any suggestion? especially how to get No 1 step done? Creating the mirrored root pool is easy enough and install time - just save the SSD for the guest virtual disks. All of this is in absence of the actual performance characteristics you expect, but that's a reasonable starting point. I hope that's useful...
