zfs-discuss mailing list & opensolaris EOL
So, I hear, in a couple weeks'' time, opensolaris.org is shutting down. What does that mean for this mailing list? Should we all be moving over to something at illumos or something? I''m going to encourage somebody in an official capacity at opensolaris to respond... I''m going to discourage unofficial responses, like, illumos enthusiasts etc simply trying to get people

Dedicated server running ESXi with no RAID card, ZFS for storage?
Morning all... I have a Dedicated server in a data center in Germany, and it has 2 3TB drives, but only software RAID. I have got them to install VMWare ESXi and so far everything is going ok... I have the 2 drives as standard data stores... But i am paranoid... So, i installed Nexenta as a VM, gave it a small disk to boot off and 2 1Tb disks on separate physical drives... I have created a

Zil on multiple usb keys
This might be a stupid question, but here goes... Would adding, say, 4 4 or 8gb usb keys as a zil make enough of a difference for writes on an iscsi shared vol? I am finding reads are not too bad (40is mb/s over gige on 2 500gb drives stripped) but writes top out at about 10 and drop a lot lower... If I where to add a couple usb keys for zil, would it make a difference? Thanks. Sent from a

iscsi confusion
I am confused, because I would have expected a 1-to-1 mapping, if you create an iscsi target on some system, you would have to specify which LUN it connects to. But that is not the case... I read the man pages for sbdadm, stmfadm, itadm, and iscsiadm. I read some online examples, where you first "sbdadm create-lu" which gives you a GUID for a specific device in the system, and then

Building an On-Site and Off-Size ZFS server, replication question
Good morning. I am in the process of planning a system which will have 2 ZFS servers, one on site, one off site. The on site server will be used by workstations and servers in house, and most of that will stay in house. There will, however, be data i want backed up somewhere else, which is where the offsite server comes in... This server will be sitting in a Data Center and will have some storage

zvol wrapped in a vmdk by Virtual Box and double writes?
Hi folks, (Long time no post...) Only starting to get into this one, so apologies if I''m light on detail, but... I have a shiny SSD I''m using to help make some VirtualBox stuff I''m doing go fast. I have a 240GB Intel 520 series jobbie. Nice. I chopped into a few slices - p0 (partition table), p1 128GB, p2 60gb. As part of my work, I have used it both as a RAW

add device to mirror rpool in sol11exp
In my new oracle server, sol11exp, it''s using multipath device names... Presently I have two disks attached: (I removed the other 10 disks for now, because these device names are so confusing. This way I can focus on *just* the OS disks.) 0. c0t5000C5003424396Bd0 <SEAGATE-ST32000SSSUN2.0-0514 cyl 3260 alt 2 hd 255 sec 252> /scsi_vhci/disk at g5000c5003424396b

encfs on top of zfs
Dear ZFS-Users, I want to switch to ZFS, but still want to encrypt my data. Native Encryption for ZFS was added in "ZFS Pool Version Number 30<http://en.wikipedia.org/wiki/ZFS#Release_history>", but I''m using ZFS on FreeBSD with Version 28. My question is how would encfs (fuse encryption) affect zfs specific features like data Integrity and deduplication? Regards

ZFS and TRIM
My google-fu is coming up short on this one... I didn''t see that it had been discussed in a while ... What is the status of ZFS support for TRIM? For the pool in general... and... Specifically for the slog and/or cache??? -------------- next part -------------- An HTML attachment was scrubbed... URL:

ZFS on top of ZFS iSCSI share
I have a filer running Opensolaris (snv_111b) and I am presenting a iSCSI share from a RAIDZ pool. I want to run ZFS on the share at the client. Is it necessary to create a mirror or use ditto blocks at the client to ensure ZFS can recover if it detects a failure at the client? Thanks, Bruin

SAS/short stroking vs. SSDs for ZIL
Hi, as I have learned from the discussion about which SSD to use as ZIL drives, I stumbled across this article, that discusses short stroking for increasing IOPs on SAS and SATA drives: http://www.tomshardware.com/reviews/short-stroking-hdd,2157.html Now, I am wondering if using a mirror of such 15k SAS drives would be a good-enough fit for a ZIL on a zpool that is mainly used for file

Best way to measure performance of ZIL
Hi all, I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of their exaggerated claims of sustained performance. I was thinking about getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive, one of the STEC products, etc. Of course the key question i''m trying to answer is: is the price premium worth it? --- What is the (average/min/max)

a single nfs file system shared out twice with different permissions
I am trying to configure a system where I have two different NFS shares which point to the same directory. The idea is if you come in via one path, you will have read-only access and can''t delete any files, if you come in the 2nd path, then you will have read/write access. For example, create the read/write nfs share: zfs create tank/snapshots zfs set sharenfs=on tank/snapshots root

ZFS Appliance as a general-purpose server question
A customer is looking to replace or augment their Sun Thumper with a ZFS appliance like 7320. However, the Thumper was used not only as a protocol storage server (home dirs, files, backups over NFS/CIFS/Rsync), but also as a general-purpose server with unpredictably-big-data programs running directly on it (such as corporate databases, Alfresco for intellectual document storage, etc.) in order to

Resliver making the system unresponsive
This must be resliver day :) I just had a drive failure. The hot spare kicked in, and access to the pool over NFS was effectively zero for about 45 minutes. Currently the pool is still reslivering, but for some reason I can access the file system now. Resliver speed has been beaten to death I know, but is there a way to avoid this? For example, is more enterprisy hardware less susceptible to

Have my RMA... Now what??
I have a raidz2 pool with one disk that seems to be going bad, several errors are noted in iostat. I have an RMA for the drive, however - no I am wondering how I proceed. I need to send the drive in and then they will send me one back. If I had the drive on hand, I could do a zpool replace. Do I do a zpool offline? zpool detach? Once I get the drive back and put it in the same drive bay..

multipl disk failures cause zpool hang
Hi, There seems to be a few threads about zpool hang, do we have a workaround to resolve the hang issue without rebooting ? In my case, I have a pool with disks from external LUNs via a fiber cable. When the cable is unplugged while there is IO in the pool, All zpool related command hang (zpool status, zpool list, etc.), put the cable back does not solve the problem. Eventually, I

Intel 320 as ZIL?
Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

Changing rpool device paths/drivers
Hello all, It was often asked and discussed on the list about "how to change rpool HDDs from AHCI to IDE mode" and back, with the modern routine involving reconfiguration of the BIOS, bootup from separate live media, simple import and export of the rpool, and bootup from the rpool. The documented way is to reinstall the OS upon HW changes. Both are inconvenient to say the least.
