similar to: Sector size on 7K3000 drives?

Still have good quality older sata hardware raid cards that require 512 bytes/sector. As far as I know HD manufacturers are not making native 512 bytes/sector drives any more. Some have better 512e emulation than others. Looking for some advice on which to avoid and which are recommended. Thanks. PS this is for a CentOS6 server.

Hi all One of the rpool drives on this server died the other day, so I got a replacement that was 1 cylinder larger (60798 vs 60797). Still, I tried prtvtoc /dev/rdsk/c7d0s2 | fmthard -s - /dev/rdsk/c6d0s2 zpool replace worked and the pool resilvered within a few minutes. Now, installing grub fails. root at prv-backup:~# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c6d0s0

hi all I have a server running svn_131 and the scrub is very slow. I have a cron job for starting it every week and now it''s been running for a while, and it''s very, very slow scrub: scrub in progress for 40h41m, 12.56% done, 283h14m to go The configuration is listed below, consisting of three raidz2 groups with seven 2TB drives each. The root fs is on a pair of X25M (gen 1)

Hi I keep getting these messages on this one box. There are issues with at least one of the drives in it, but since there are some 80 drives in it, that''s not really an issue. I just want to know, if anyone knows, what this kernel message mean. Anyone?

Hi all Has anyone done any testing with dedup with OI? On opensolaris there is a nifty "feature" that allows the system to hang for hours or days if attempting to delete a dataset on a deduped pool. This is said to be fixed, but I haven''t seen that myself, so I''m just wondering... I''ll get a 10TB test box released for testing OI in a few weeks, but before

Hi all I''m seeing some rather bad resilver times for a pool of WD Green drives (I know, bad drives, but leave that). Does resilver go through the whole pool or just the VDEV in question? -- Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy at karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres

Hi all Having managed ZFS for about two years, I want to post a wishlist. INCLUDED IN ZFS - Mirror existing single-drive filesystem, as in ''zfs attach'' - RAIDz-stuff - single and hopefully multiple-parity RAID configuration with block-level checksumming - Background scrub/fsck - Pool-like management with multiple RAIDs/mirrors (VDEVs) - Autogrow as in ZFS autoexpand NOT

Hi all We're considering getting some Powerware 9355-30-M-0 UPSes to replace some older ones, so I wonder if it would be possible to use NUT for this. It seems 9315 is supported, but AFAICS that's the top model.

Hi all I have a box running Debian Lenny 5.0.1 and Dovecot 1.0.15. The user query given below does not expand %d, making logins fail. The password query seems to work well, according to the mysql query log. Any ideas why this happens? Best regards roy user_query = SELECT 'maildir:/var/spool/dovecot/%d/%n' as mail, uid, gid, domain FROM users WHERE username = '%n' and

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't

Hi all Trying to setup dovecot with mysql and postfix, I have configured it as given below. thecot user has the dovecot group as primary, and is also a member of mail and dovecot-users. Still, it can't setgid to dovecot-users. I tried changing the shell for the dovecot user to something useful and chmod'ing a file to dovecot-users, and it work well. Still, no mail comes through

hi We have a box here connected to an antenna receiving rather large amounts of metheorological data from a satellite. the data is received and ransferred to another box and removed from the receiving server. I first thought of using rsync for this, but it seems --remove-source- files has no way of checking if the file is open or not, so if the receiving process is still writing to a

Hi all I have installed a new server with 77 2TB drives in 11 7-drive RAIDz2 VDEVs, all on WD Black drives. Now, it seems two of these drives were bad, one of them had a bunch of errors, the other was very slow. After zfs offlining these and then zfs replacing them with online spares, resilver ended and I thought it''d be ok. Appearently not. Albeit the resilver succeeds, the pool status

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 this server with some 50TB disk space. It originally had 30TB on WD Greens, was filled quite full, and another storage chassis was added. Now, space problem gone, fine, but what about speed? Three of the VDEVs are quite full, as indicated below. VDEV #3 (the one with the spare active) just spent some 72 hours resilvering a 2TB drive. Now, those green drives suck quite hard, but not

Hi, I'm trying to boot Feature Tool 2.08 (free download from http://www.hitachigst.com/hdd/support/download.htm) from a pen drive via memdisk.

Hey all, I recently updated to syslinux 3.83, I am getting machines rebooting or locking after loading PC DOS. Most notably with Hitachi's Disk Fitness Test (http://www.hitachigst.com/hdd/support/download.htm#DFT) Version 4.16. At first it was a trickle, and now it seems I am having the issue with more hardware. I downgraded to syslinux 3.81, and everything is happy again. The Current

hpa, Seeing your post about 3.71, I wanted to get a message out even though I don't have the stats right now. I am having a problem with memdisk with a lot of shuttle computers, but also affects a variety of other hardware (low though, 5%? less?). The image that I can most reliably test against is the Hitachi Drive fitness Test.
