similar to: Dedicated server running ESXi with no RAID card, ZFS for storage?

Hello All, I have a zpool that consists of 2 raidz vdevs (raidz1-0 and raidz1-1). The first vdev is 4 1.5TB drives. The second was 4 500GB drives. I replaced the 4 500GB drives with 4 3TB drives. I replaced one at time, and resilvered each. Now the process is complete, I expected to have an extra 10TB (4*2.5TB) of raw space, but it''s still the same amount of space. I did an export and

Hi there. How can I configure dovecot not to listen for imaps connections on port 143. Thanks Lars

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

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

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)

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

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

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:

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

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

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

Hi, after a flaky 8-drive Linux RAID10 just shredded about 2 TByte worth of my data at home (conveniently just before I could make a backup) I''ve decided to both go full redundancy as well as all zfs at home. A couple questions: is there a way to make WD20EFRX (2 TByte, 4k sectors) and WD200FYPS (4k internally, reported as 512 Bytes?) work well together on a current OpenIndiana? Which

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

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

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 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

Hi I wanted to get some expert advice on this. I have an ordinary hardware SAN from Promise Tech that presents the LUNs via iSCSI. I would like to use that if possible with my VMware environment where I run several Solaris / OpenSolaris virtual machines. My question is regarding the virtual disks. 1. Should I create individual iSCSI LUNs and present those to the VMware ESXi host as iSCSI storage,

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

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..

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
