Hi, I could not find any hints about hotspares with zfs. Are hotspares not possible? Thanks for this really great filesystem Willi

Hello, I need to setup a NAS server on Centos. The machine will be: Dual xeon/Dual Opteron 4GB memory 13x 320GB SATA + 1 hotspare 1x 320GB SATA for OS The server can do RAID5,6,or 10. Has anyone installed such a software and can you recommand a specific product? Thank you.

Hi, I have been trying to install CentOS 5.4 on a Intel SR1530SHS, Intel S3200SH mainboard.. It has a 3 x 1TB sata hotswap drives with LSI software raid onboard. I had configured the LSI to have Sata0 and Sata1 with raid 1 and the third drive as a hotspare drive. Format the harddisk and installation was a breeze. The server rebooted into a blank screen and the cursor just keep blinking. Please advise. Thanks wL

...ur HP NetServers, two LC2000r and two LH6000r. the CentOS 4.2 ServerCD can't see hard drives on any of them. each machine has a HP NetRAID controller; the LC2000rs have a NetRAID-1Si and the LH6000rs have an Integrated NetRAID. each controller has three 9GB drives, two mirrored and one hotspare. each machine boots ok (the LC2000rs need "linux noacpi" or they complain about being in a weird power management state and panic), each loads the megaraid driver, but none of them can see any volumes. fixes i have already tried: 1) on the LH6000rs i have disabled "Smart IRQ&...

I just had an IBM in a remote location with a hardware raid1 have both drives go bad. With local machines I probably would have caught it from the drive light before the 2nd one died... What is the state of the art in linux software monitoring for this? Long ago when that box was set up I think the best I could have done was a Java GUI tool that IBM had for their servers - and that seemed like

Hi, I've used mdadm for years now to manage software raids. The task of using fdisk to first create partitions on a spare drive sitting on a shelf (raid 0 were my 1st of 2 drives failed) is kind of bugging me now. After using fdisk to create the same partition layout on the new drive as is on the existing drive and then using mdadm to finish every thing up is a little tedious. Any

Can someone point me for good VRRPD (rfc2338) implementation on linux. Some stable and live project Thanks _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

...will take a long time. The problem was/is the Hash-Algo. So I'm asking me how is it if I've one very big brick (Raid10 20TB on each server) or I've much more bricks, what's faster and is there any issues? Is there any experiences ? 3) Failover of a HDD is for a raid controller with HotSpare HDD not a big deal. Glusterfs will rebuild automatically if a brick fails and there are no data present, this action will perform a lot of network traffic between the mirror bricks but it will handle it equal as the raid controller right ?

Does anyone know what program can be used to query the RAID status from the OS for an on-board LSI SAS 2308-4i? On this page: http://docs.avagotech.com/docs/12351997 there is a curious note on the left that reads: "Integrated MegaRAID support available upon request" After one mostly fruitless round of chatting with LSI/Avago/Broadcom and one completely fruitless round of chatting

Hello fellow CentOS'ers- I've got a system running CentOS 5.0. The motherboard has two onboard SATA ports with two drives attached. I installed the system on a RAID1 setup. However, I'd like to add a hotspare disk to the array. Since there are no additional SATA ports, I've installed an additional controller. After partitioning, the additional drive was easily and successfully added to the existing array as a spare. However, the problem is when the system boots. The hotspare disk is never detected...

Hello All I have a brand spanking new 40TB Hardware Raid6 array to play around with. I am looking for recommendations for which filesystem to use. I am trying not to break this up into multiple file systems as we are going to use it for backups. Other factors is performance and reliability. CentOS 5.6 array is /dev/sdb So here is what I have tried so far reiserfs is limited to 16TB ext4

This must be resliver day :) I just had a drive failure. The hot spare kicked in, and access to the pool over NFS was effectively zero for about 45 minutes. Currently the pool is still reslivering, but for some reason I can access the file system now. Resliver speed has been beaten to death I know, but is there a way to avoid this? For example, is more enterprisy hardware less susceptible to

Hi, everyone! I have a beginner''s question: I must configure a small file server. It only has two disk drives, and they are (forcibly) destined to be used in a mirrored, hot-spare configuration. The OS is installed and working, and rpool is mirrored on the two disks. The question is: I want to create some ZFS file systems for sharing them via CIFS. But given my limited configuration:

...I have some questions: a) if i want to boot from every disk in case of error, i have to setup grub on every disk, such that if the controller sets this disk as the booting, the rootpool is able to be loaded from that. b) what is the best way to as fast as possible replace a disk. adding a disk as hotspare for the raidz is a good idea. but i also would like to replace the disk during runtime as simple as possible. the problem is that for the root pool the disks are labeled (the slices thingy). So I cannot simply detach the volumes and replace the disk and attach them again, but I have to format th...
