similar to: hardware sizing for a zfs-based system?

I just installed CentOS 4.1 for the first time - I did a "minimal install"... Now I'm trying to install Xen - according to several online resources I should just be able to run `yum install xen`, but yum never finds the package - though tcpdump shows http traffic going to lists.centos.org: [root at centos ~]# yum install xen Setting up Install Process Setting up Repos update

ZFS Fans, Here''s a list of features that we are proposing for Solaris 10u5. Keep in mind that this is subject to change. Features: PSARC 2007/142 zfs rename -r PSARC 2007/171 ZFS Separate Intent Log PSARC 2007/197 ZFS hotplug PSARC 2007/199 zfs {create,clone,rename} -p PSARC 2007/283 FMA for ZFS Phase 2 PSARC/2006/465 ZFS Delegated Administration PSARC/2006/577 zpool property to

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

Last night I upgraded from b127 to b130 and now I can''t mark autostart domains: # virsh autostart lunar-1 error: Failed to mark domain lunar-1 as autostarted error: failed to serialize S-Expr: (domain (on_crash restart) (uuid 91c21040-2098-bc0d-b401-3908f3a21667) (bootloader_args) (vcpus 1) (name lunar-1) (on_poweroff destroy) (on_reboot restart) (cpus ( Searching the archives

Hi Folks, I was wondering if anyone has an pointers/suggestions on how I might increase disk performance of a HVM zvol-backed DomU? - this is my first DomU, so hopefully its something obvious Running bonnie++ shows the DomU''s performance to be 3 orders of magnitude worse than Dom0''s, which itself is half as good as when not running xVM at all (see bottom for bonnie++ results)

for s10u2, documentation recommends 3 to 9 devices in raidz. what is the basis for this recommendation? i assume it is performance and not failure resilience, but i am just guessing... [i know, recommendation was intended for people who know their raid cold, so it needed no further explanation] thanks... oz -- ozan s. yigit | oz at somanetworks.com | 416 977 1414 x 1540 I have a hard time

Hey all, I''m not sure if this is a ZFS bug or a hardware issue I''m having - any pointers would be great! Following contents include: - high-level info about my system - my first thought to debugging this - stack trace - format output - zpool status output - dmesg output High-Level Info About My System --------------------------------------------- - fresh

Hi All, I am about to embark on a project that deals with allowing information archival, over time and seeing change over time as well. I can explain it a lot better, but I would certainly talk your ear off. I really don't have a lot of money to throw at the initial concept, but I have some. This device will host all of the operations for the first few months until I can afford to build a

Short:     Which package do I need to install to get "auto/I18N/Langinfo/autosplit.ix"? Long: The problem I have was discussed almost a year ago (see this thread), but the resolution was not complete... I''m using Mark Johnson''s slim.py script (package list below), against repo=http://pkg.opensolaris.org/dev, followed by `pkg install xvm-gui` and `svcadm enable

I''m a fan of ZFS since I''ve read about it last year. Now I''m on the way to build a home fileserver and I''m thinking to go with Opensolaris and eventually ZFS!! Apart from the other components, the main problem is to choose the motherboard. The offer is incredibly high and I''m lost. Minimum requisites should be: - working well with Open Solaris ;-) -

Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would

I''m putting together a NexentaOS (b65)-based server that has 4 500 GB drives on it. Currently it has two, set up as a ZFS mirror. I''m able to boot Nexenta from it, and it seems to work ok. But, as I''ve learned, the mirror is not properly redundant, and so I can''t just have a drive fail (when I pull one, the OS ends up hanging, and even if I replace it, I have 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.

Is there anyone who has successfully put together a "high-powered" mini-itx ZFS box that would be willing to post their system specs? I''m eyeballing the KI690-AM2... http://www.albatron.com.tw/english/product/mb/pro_detail.asp?rlink=Overview&no=239 ...but am having a difficult time locating it and a suitable case currently. I was in negotiations with a hardware source,

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to

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,

I have an admin machine, and a backup server which does backups. The backup server has IPMI so I can do lights-out admin, and I want to allow this from the admin machine only. IPMI is completely unfirewalled, and so it must have a different class C than working networks.... this is just how it is. I''ve set the IPMI IP on the backup server to 192.168.10.4, and created a virtual

Hi list, i have seen a lot of questions about VT-d on recent intel mobos. however, it seems that all tests are done on the newer socket 775-based xeon''s or core2''s, and not the 5000 series (socket 771 based). i was planning on getting a intel S5000V chipset, but found out that it does not support VT-d. Can anyone confirm a mobo that has this enabled and also has 2x LGA771

According to various posts the LSI SAS3081E-R seems to work well with OpenSolaris. But I''ve got pretty chilled-out from my recent problems with Areca-1680''s. Could anyone please confirm that the LSI SAS3081E-R works well ? Is hotplug supported ? Anything else I should know before buying one of these cards ? Thanks, Arnaud

Hi Ged; At the moment ZFS is not a shared file system nor a paralell file system. However lustre integration which will take some time will provide parallel file system abilities. I am unsure if lustre at the moment supports redundancy between storage nodes (it was on the road map) But ZFS at the moment supports Sun cluster 3.2 (no paralel acccess is supported) and new upcoming SAS Jbods
