similar to: Recommendation for home NAS external JBOD

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

Greetings, Quick question: I am about to acquire some disks for use with ZFS (currently using zfs-fuse v0.7.0). I''m aware of some 4k alignment issues with Western Digital advanced format disks. As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses 512B sectors and so I presume does not suffer from such issues (because it doesn''t lie about the physical layout

HI All, I have a dilemma and I would appreciate advice 1. Get a good size case, mobo, processor, etc and put 8 hard drives it in and RAID them. (yes an 8 port SATA mobo). Running CentOS. or 2. Get an eSATA enclosure that has room for 8 or 10 drives and just connect it to box? I know that RAID is not a full proof backup, but I am looking for a solution to store all of my data, projects, music,

Hi. Is the problem with ZFS supporting 4k sectors or is the problem mixing 512 byte and 4k sector disks in one pool, or something else? I have seen alot of discussion on the 4k issue but I haven''t understood what the actual problem ZFS has with 4k sectors is. It''s getting harder and harder to find large disks with 512 byte sectors so what should we do? TIA...

zdb -C shows an shift value on each vdev in my pool, I was just wondering if it is vdev specific, or pool wide. Google didn''t seem to know. I''m considering a mixed pool with some "advanced format" (4KB sector) drives, and some normal 512B sector drives, and was wondering if the ashift can be set per vdev, or only per pool. Theoretically, this would save me some size on

Well Solaris SAS isn''t there yet but anyway just found some interesting high density SAS/SATA enclosures. <http://xtore.com/product_list.asp?cat=JBOD> The XJ 2000 is like the x4500 in that it holds 48 drives, however with the XJ 2000 2 drives are on each carrier and you can get to them from the front. I don''t like xtore in general but the 24 bay (2.5" SAS) and 48

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

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.

Happy Friday, List! I''m spec''ing out a Thumper-esque solution and having trouble finding my favorite Hitachi Ultrastar 2TB drives at a reasonable post-flood price. The Seagate Constellations seem pretty reasonable given the market circumstances but I don''t have any experience with them. Anybody using these in their ZFS systems and have you had good luck? Also, if

I'm looking at buying a NORCO DS-1220 and it comes with a NORCO 4618 PCI-X card (4 port eSATA, with a port multiplier on the card or the chassis). I've been trying to pin down whether or not CentOS will see all 12 drives, and I haven't seen anything that is definitive. I see that the kernel module sata_sil24 supports the SiI3124 chip on the NORCO 4618 card, but I haven't found

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

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 all, I would like to knwon if with ZFS it''s possible to do something like that : http://tldp.org/HOWTO/LVM-HOWTO/removeadisk.html meaning : I have a zpool with 48 disks with 4 raidz2 (12 disk). Inside those 48 disk I''ve 36x 3T and 12 x 2T. Can I buy new 12x4 To disk put in the server, add in the zpool, ask zpool to migrate all data on those 12 old disk on the new and

My setup: A SuperMicro 24-drive chassis with Intel dual-processor motherboard, three LSI SAS3081E controllers, and 24 SATA 2TB hard drives, divided into three pools with each pool a single eight-disk RAID-Z2. (Boot is an SSD connected to motherboard SATA.) This morning I got a cheerful email from my monitoring script: "Zchecker has discovered a problem on bigdawg." The full output is

Nick, What are you planning on running over the shared connection? Database, eMail, File Shares? How many users? How much data? What is your I/O profile? I've worked with 'enterprise' storage most of my career either as a consumer, adviser or provider - can't comment on AoE other than to suggest you look at what are the business & technical goals, how they solve it and what

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

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

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?

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
