Re: [zfs-discuss] Can the new consumer NAS devices run OpenSolaris?
Hello Jorgen I used a VIA SN18000 itx board housed in a chenbro mini case (http://www.chenbro.com/corporatesite/products_detail.php?sku=79) that can hold up to 4 sata drives ( hot pluggable) dvd drive and internal ide. Can boot from flash via IDE, have not tried that yet. Neat little setup. Peter Jorgen Lundman wrote: Re-surfacing an old thread. I was wondering myself if there are any home-use commercial NAS devices with zfs. I did find that there is Thecus 7700. But, it appears to come with Linux, and use ZFS in FUSE, but I (perhaps unjustly) don't feel comfortable with :) Perhaps we will start to see more home NAS devices with zfs options, or at least to be able to run EON ? Joe S wrote: In the last few weeks, I've seen a number of new NAS devices released from companies like HP, QNAP, VIA, Lacie, Buffalo, Iomega, Cisco/Linksys, etc. Most of these are powered by Intel Celeron, Intel Atom, AMD Sempron, Marvell Orion, or Via C7 chips. I've also noticed that most allow a maximum of 1 or 2 GB of RAM. Is it likely that any of these will run OpenSolaris?

If you add zpool send/receive and geographically dislocated severs, this may be better than optical media, because you detect the errors early. Two things to be aware of with this type of statistical info ( also true for MTBF ), It is statistical info and it is an average, it does not give any guarantee that a catastrophic event will not happen in the next hr. Secondly this figure is defined on subsystem level, if the box goes up in smoke the thousands of years MTTDL is of no use! So the moral of the story is to always plan for a second copy of your data if you want to design resilience from a data set point of view. -- Regards Peter Brouwer, Sun Microsystems Linlithgow Principal Storage Architect, ABCP DRII Consultant Office:+44 (0) 1506 672767 Mobile:+44 (0) 7720 598226 Skype :flyingdutchman_,flyingdutchman_l smime.p7s Description: S/MIME Cryptographic Signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Hello abs Would you be able to repeat the same tests for the cifs in zfs option instead of using samba? Would be interesting to see how the kernel cifs versus the samba performance compare. Peter abs wrote: hello all, i have two xraids connect via fibre to a poweredge2950. the 2 xraids are configured with 2 raid5 volumes each, giving me a total of 4 raid5 volumes. these are striped across in zfs. the read and write speeds local to the machine are as expected but i have noticed some performance hits in the read and write speed over nfs and samba. here is the observation: each filesystem is shared via nfs as well as samba. i am able to mount via nfs and samba on a Mac OS 10.5.2 client. i am able to only mount via nfs on a Mac OS 10.4.11 client. (there seems to be authentication/encryption issue between the 10.4.11 client and solaris box in this scenario. i know this is a bug on the client side) when writing a file via nfs from the 10.5.2 client the speeds are 60 ~ 70 MB/sec. when writing a file via samba from the 10.5.2 client the speeds are 30 ~ 50 MB/sec when writing a file via nfs from the 10.4.11 client the speeds are 20 ~ 30 MB/sec. when writing a file via samba from a Windows XP client the speeds are 30 ~ 40 MB. i know that there is an implementational difference in nfs and samba on both Mac OS 10.4.11 and 10.5.2 clients but that still does not explain the Windows scenario. i was wondering if anyone else was experiencing similar issues and if there is some tuning i can do or am i just missing something. thanx in advance. cheers, abs Never miss a thing.

[zfs-discuss] boot from zfs, mirror config issue
2008-03-26
Thread
Peter Brouwer, Principal Storage Architect, Office of the Chief Technologist, Sun MicroSystems
Hello, I ran into the following issue when configuring a system with ZFS for root. The restriction is that it can only be either a single disk or a mirror pool for root. Trying to set bootfs on a zpool that does not satisfy the above criteria fails, so this is good. However when adding a mirror set to the zpool like zpool add rootpool mirror disk3 disk 4 is not blocked. Once this command is executed you are toast as you cannot remove the extra mirror. Executing zpool set bootfs now fails. If this is general zfs behavior , would it not be better for zpool to check if bootfs is set and refuse any zpool add command that compromises the boot restrictions of the pool bootfs is set for. -- Regards Peter Brouwer, Sun Microsystems Linlithgow Principal Storage Architect, ABCP DRII Consultant Office:+44 (0) 1506 672767 Mobile:+44 (0) 7720 598226 Skype :flyingdutchman_,flyingdutchman_l smime.p7s Description: S/MIME Cryptographic Signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] zpool automount issue

Thread

Hello, I ran into an issue with the automount feature of zpool. Normal default behavior is for the pool and filesystems in it to be automatically mounted, unless you set zfs/zpool set mountpoint=[legacy|/yourname] When I used 'export' as pool name I could not get it to automount. Wonder if export is a reserved name as it is part of the zpool command syntax. Anyone seen this too? Used the nexenta opensolaris derivative. -- Regards Peter Brouwer, Sun Microsystems Linlithgow Principal Storage Architect, ABCP DRII Consultant Office:+44 (0) 1506 672767 Mobile:+44 (0) 7720 598226 Skype :flyingdutchman_,flyingdutchman_l smime.p7s Description: S/MIME Cryptographic Signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
