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

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:

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

I''m looking for a way to backup my entire system, the rpool zfs pool to an external HDD so that it can be recovered in full if the internal HDD fails. Previously with Solaris 10 using UFS I would use ufsdump and ufsrestore, which worked so well, I was very confident with it. Now ZFS doesn''t have an exact replacement of this so I need to find a best practice to replace it.

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

I''ve hit this bug on four of my Solaris 11 servers. Looking for anyone else who has seen it, as well as comments/speculation on cause. This bug is pretty bad. If you are lucky you can import the pool read-only and migrate it elsewhere. I''ve also tried setting zfs:zfs_recover=1,aok=1 with varying results. http://docs.oracle.com/cd/E26502_01/html/E28978/gmkgj.html#scrolltoc

I have a Dell R710 which has been flaky for some time. It crashes about once per week. I have literally replaced every piece of hardware in it, and reinstalled Sol 10u9 fresh and clean. I am wondering if other people out there are using Dell hardware, with what degree of success, and in what configuration? The failure seems to be related to the perc 6i. For some period around the time

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

On Solaris 10 If I install using ZFS root on only one drive is there a way to add another drive as a mirror later? Sorry if this was discussed already. I searched the archives and couldn''t find the answer. Thank you.

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

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

"Does raidzN actually protect against bitrot?" That''s a kind of radical, possibly offensive, question formula that I have lately. Reading up on theory of RAID5, I grasped the idea of the write hole (where one of the sectors of the stripe, such as the parity data, doesn''t get written - leading to invalid data upon read). In general, I think the same applies to bitrot of

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

Banging my head against a Seagate 3TB USB3 drive. Its marketing name is: Seagate Expansion 3 TB USB 3.0 Desktop External Hard Drive STAY3000102 format(1M) shows it identify itself as: Seagate-External-SG11-2.73TB Under both Solaris 10 and Solaris 11x, I receive the evil message: | I/O request is not aligned with 4096 disk sector size. | It is handled through Read Modify Write but the performance

Hi, I am facing issue with zfs destroy, this takes almost 3 Hours to delete the snapshot of size 150G. Could you please help me to resolve this issue, why zfs destroy takes this much time. While taking snapshot, it''s done within few seconds. I have tried with removing with old snapshot but still problem is same. =========================== I am using : Release : OpenSolaris

When I search around, I see that nexenta has ndmp, and solaris 10 does not, and there was at least some talk about supporting ndmp in opensolaris ... So ... Is ndmp present in solaris 11 express? Is it an installable 3rd party package? How would you go about supporting ndmp if you wanted to? -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

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)

as used on Illumos? I''ve seen a few tutorials written by people who obviously are very action oriented; afterwards you find you have worn your keyboard down a bit and not learned a lot at all, at least not in the sense of understanding what zfs is and what it does and why things are the way they are. I''m looking for something that would make me afterwards understand what,
