My current home fileserver (running Open Solaris 111b and ZFS) has an ASUS M2N-SLI DELUXE motherboard. This has 6 SATA connections, which are currently all in use (mirrored pair of 80GB for system zfs pool, two mirrors of 400GB both in my data pool). I''ve got two more hot-swap drive bays. And I''m getting up towards 90% full on the data pool. So, it''s time to expand,

Something seems to be wrong with my file systems, and I want to fsck everything. But I cannot. The setup consists of 2 hds, carrying 3 raid1 (ext3) file systems (boot, /, swap). OS is up-to-date CentOS 5. So I boot from CentOS 5.3 dvd in rescue mode, do not mount the file systems, and try to run fsck -y /dev/md0 fsck -y /dev/md1 fsck -y /dev/md2 For each try I get an error message:

Might be slightly OT as it isn't necessarily a CentOS related issue. I've been using WD Reds as mdraid components which worked pretty well for non-IOPS intensive workloads. However, the latest C7 server I built, ran into problems with them on on a Intel C236 board (SuperMicro X11SSH) with tons of "ata bus error write fpdma queued". Googling on it threw up old suggestions to

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

Hello, Just a couple questions regarding RAID. Here's thesituation. I bought a 4TB drive before I upgraded from 6.8 to 7.3. I'm not too far into this that Ican't start over. I wanted disk space to backup 3 other machines. I way overestimated what I needed for full, incremental and image backups with UrBackup.I've used less than 1TB so far. I would like to add an additional drive

I need the community''s opinion on the best way to use my storage SAN to host xen images. The SAN itself is running iSCSI and NFS. My goal is to keep all my xen images on the SAN device, and to be able to easily move images from one host to another as needed while minimizing storage requirements and maximizing performance. What I see are my options: 1) Export a directory through NFS.

I have a DAS w/ 6 750Gb and 6 1Tb discs I am setting up using Linux raid. The controller is a POS so each disc is exported as an R0 single volume. I used a parted and fdisk script to create 1 max size partition labeled as Linux Raid Autodetect and created the first r6 array w/ mdadm. I normally create and mark partitions as raid or lvm so people know what's going on. The first md array is

I have 3 4TB WD drives I want to put in a RAID1 array. Two WD4000FYYZ and One WD4000F9YZ All enterprise class but two are WD Re and one is WD Se. I ordered the first two thinking 2 drives in the raid array would be sufficient but later decided its a long drive to the server so I would rather have 3 drives and ordered a third in accidentally did not get EXACT same thing. Would there be ANY

'--no-degraded' flag in the first mdadm call inhibits the startup of array unless all expected drives are present. This will prevent starting arrays in degraded state. Second mdadm call (after LVM is scanned) will scan unused yet devices and make an attempt to run all found arrays even they are in degraded state. Two new tests are added. This fixes rhbz1527852. Here is boot-benchmark

Hi list, I'm building a backup server for 3 hosts (1 workstation, 2 server). I will use bacula to perform backups. The backup is performed on disks (2 x 3TB on mdraid mirror) and for each hosts I've created a logical volume with related size. This 3 hosts have different data size with different disk change rate. Each host must have a limited sized resource and a reserved space. If a

Hello, I am new to open solaris and am trying to setup a ZFS based storage solution. I am looking at setting up a system with the following specs: Intel BOXDG33FBC Intel Core 2 Duo 2.66Ghz 2 or 4 GB ram For the drives I am looking at using a LSI SAS3081E-R I''ve been reading around and it sounds like LSI solutions work well in terms of compatability with solaris. Could someone help

Can anybody tell me if it makes a difference if domU''s have separate LVM volume groups? For instance, the Xen User Manual ( http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03330000000000000000) says, when setting up a domU''s disks with LVM, to do a vgcreate vg /dev/sda10 Should each domU have it''s own volume group, or can all the domU''s share
