Hi, my oi151 based home NAS is approaching a frightening "drive space" level. Right now the data volume is a 4*1TB Raid-Z1, 3 1/2" local disks individually connected to an 8 port LSI 6Gbit controller. So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks and be happy. This was my original approach. However I am totally unclear about the 512b vs 4Kb issue.

Hello, Has anyone out there been able to qualify the Proliant DL360 G7 for your Solaris/OI/Nexenta environments? Any pros/cons/gotchas (vs. previous generation HP servers) would be greatly appreciated. Thanks in advance! -Anh

Hi all, Space is starting to get a bit tight here, so I''m looking at adding a couple of TB to my home server. I''m considering external USB or FireWire attached drive enclosures. Cost is a real issue, but I also want the data to be managed by ZFS--so enclosures without a JBOD option have been disgarded (i.e., I don''t want to use any internal HW RAID controllers). One

apparently if you don''t order a J4200 with drives, you just get filler sleds that won''t accept a hard drive. (had to look at a parts breakdown on sunsolve to figure this out -- the docs should simply make this clear.) it looks like the sled that will accept a drive is part #570-1182. anyone know how i could order 12 of these?

ZFS fans, I''m preparing some analyses on RAS for large JBOD systems such as the Sun Fire X4500 (aka Thumper). Since there are zillions of possible permutations, I need to limit the analyses to some common or desirable scenarios. Naturally, I''d like your opinions. I''ve already got a few scenarios in analysis, and I don''t want to spoil the brain storming, so

Hi, Does anyone have experiences about ARC-1883I SAS controller with CentOS7? I am planning to have RAID1 setup and I am wondering if I should use the controller's RAID functionality which has 2GB cache or should I go with JBOD + Linux software RAID? The disks I am going to use are 6TB Seagate Enterprise ST6000NM0034 7200rpm SAS/12Gbit 128 MB If hardware RAID is preferred, the

Hi, I know (from the zfs-discuss archives and other places [1,2,3,4]) that a lot of people are looking to use zfs as a storage server in the 10-100TB range. I''m in the same boat, but I''ve found that hardware choice is the biggest issue. I''m struggling to find something which will work nicely under solaris and which meets my expectations in terms of hardware.

Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

I have 15x SAS drives in a Dell MD1000 enclosure, attached to an LSI 9200-16e. This has been working well. The system is boothing off of internal drives, on a Dell SAS 6ir. I just tried to add a second storage enclosure, with 15 more SAS drives, and I got a lockup during Loading Kernel. I got the same results, whether I daisy chained the enclosures, or plugged them both directly into the LSI

Working on my ZFS Build, using a SuperMicro 846E1 chassis and an LSI 1068e SAS controller, I''m wondering how well FM works in OpenSolaris 2009.06. I''m hoping that if ZFS detects an error with a drive, that it''ll light up the fault light on the corresponding hot-swap drive in my enclosure and any attached JBOD enclosures. How would I go about testing this? All drives

Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin

Your question is difficult to parse. Typically RAID and JBOD are mutually exclusive. By "flash-backed", do you mean a battery backup unit (BBU) on your RAID controller?

Yes the flash-backed RAID cards use a super-capacitor to backup the flash cache. You have a choice of flash module sizes to include on the card. The card supports RAID modes as well as JBOD. I do not know if Gluster can make use of battery-backed flash-based Cache when the disks are presented by the RAID card in JBOD. The Hardware vendor asked "Do you know if Gluster makes use of

So I'm curious how SAS JBOD arrays and linux MDraid as implemented in CentOS6, and SES (SCSI/SAS Enclosure Services) backplane controllers 'get along' and how much configuration is needed to get the warning lights to work properly. scenario: whitebox server with a SAS backplane or two, daisy chained on a SAS HBA (like an LSI Logic 2008), and disks organized as several raid5/6

I don't think this is off topic since I want to use JBOD mode so that Linux can do the RAID. I'm going to hopefully run this in CentOS 5 and Ubuntu 12.04 on a Sunfire x2250 Hard to get answers I can trust out of vendors :-) I have a Sun RAID card which I am pretty sure is LSI OEM. It is a 3G/s SAS1 with 2 external connectors like the one on the right here :

hi everyone, I am planning on creating a local SAN via NFS(v4) and several redundant nodes. I have been using DRBD on linux before and now am asking whether some of you have experience on on-demand network filesystem mirrors. I have yet little Solaris sysadmin know how, but i am interesting whether there is an on-demand support for sending snapshots. I.e. not via a cron job, but via a

We have 14 500GB PATA drives left over from another project. Given that ZFS seems to prefer working with jbod''s, does anyone know of an inexpensive enclosure with an fcal interface to host the disks? This message posted from opensolaris.org

Hey folks, I guess this is an odd question to be asking here, but I could do with some feedback from anybody who''s actually using ZFS in anger. I''m about to go live with ZFS in our company on a new fileserver, but I have some real concerns about whether I can really trust ZFS to keep my data alive if things go wrong. This is a big step for us, we''re a 100% windows

I''m not sure if this is the right place for the question or not, but I''ll throw it out there anyways. Does anyone know, if you create your pool(s) with a system running fishworks, can that pool later be imported by a standard solaris system? IE: If for some reason the head running fishworks were to go away, could I attach the JBOD/disks to a system running snv/mainline
