similar to: MegaRAID, and creating a RAID 1 while live

Thank you for your help.

My firmware seems to be more up to date. Anyway, I will try to update firmware. I have to check how to do that. # dmesg |grep LSI scsi4 : LSI SAS

I have LSI Logic MegaRAID 8480 Storage controller I am having trouble reconfigure one of the hardware raid devices It is configured with 4 hardware raid logical volumes on /dev/sda /dev/sdb /dev/sdc /dev/sdd. I am in the middle of rebuilding the system, ?and at this point I am only using one of the volumes, /dev/sda /dev/sda, /dev/sdb, and /dev/sdd are all 2 drive raid1 mirrors I will be

We have about 50 CentOS servers with software RAID level 1 (mirroring). Each week, we swap out one of the drives (the one in the second of four hot-swap bays, only the first two of which contain drives) on each server and take them offsite for safekeeping. The problem is, the kernel seemingly randomly switches between /dev/sdb and /dev/sdc for these devices. This makes the process slower by

CentOS release 4.5 Hi All: First of all I will admit to being spoiled by my MegaRAID SCSI RAID controllers. When a drive fails on one of them I just replace the drive and carry on with out having to do anything else. I now find myself in the situation where I have a failed drive on a non-MegaRAID controller, specifically an Adaptec 29160 SCSI controller. The system is an Acer G700 with 8

OK todays problem. I have a HP N54L Microserver running centos 6.5. In this box I have a 3x2TB disk raid 5 array, which I am in the process of extending to a 4x2TB raid 5 array. I've added the new disk --> mdadm --add /dev/md0 /dev/sdb And grown the array --> mdadm --grow /dev/md0 --raid-devices=4 Now the problem the resync speed is v slow, it refuses to rise above 5MB, in general

I always(!) flash these with the IT firmware that turns them back into a

Hello, I have a server working on centos 5.7-64 minimal installation. I have 3 separate physical drives: 120 gb ssd, 2x 3tb disks for storage. My linux installation is on ssd disk, and I want to make raid 1 for these two 3tb disks and store data, like under /mnt/data. Can you please tell me the path how this is possible? Thanks for your help! Best regards, Here are some output of commands I

I've got a box running C7, just updated (yesterday). It had an onboard RAID controller, and an HBA. I just installed a new, additional RAID card, all LSI. MegaCli64 only sees one controller. I can't seem to find the magic to see the others. I *know* the new card is a MegaRAID - the box it came in says so. The system sees it 1:00.0 RAID bus controller: LSI Logic / Symbios Logic SAS1078

Hi All, How can I RAID 10 on install? (the names myRAID1 and myRAID2 are just for example purposes) I select a custom layout.... /dev/sda, sdb, sdc, sdd are listed... I create a partition of Software RAID on each of sda, sdb, sdc, sdd Create a swap partition on sda? Click RAID and take sda and sdc and RAID 1 to myRAID1 Click RAID and take sdb and sdd and RAID 1 to myRAID2 Click RAID and

I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several

I installed a fresh copy of Debian 4.0 and Xen 3.1.0 SMP PAE from the binaries. I had a few issues getting fully virtualized guests up and running, but finally managed to figure everything out. Now I''m having a problem with paravirtualized guests and hoping that someone can help. My domU config: # # Configuration file for the Xen instance dev.umucaoki.org, created # by xen-tools

Basically the issue comes down to my Volume Groups not being found by this initrd, causing good ole kernel panic. initrd-2.6.12.6-xen3_12.1_rhel4.1.img [root@xen01 lvm]# uname -a Linux xen01.inside.***.com 2.6.9-22.0.2.ELsmp #1 SMP Thu Jan 5 17:13:01 EST 2006 i686 i686 i386 GNU/Linux [root@xen01 lvm]# cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 2) Everything

Hi I have setup software RAID two years ago using FC3 using the graphical installer (RAID1). In the mean time I installed CENTOS4.5 and everything is running fine. At least that was my perception. It now turns out that raid is not working and that LVS just finds 4 partitions from four disks and that's it.: /dev/sda2 VolGroup00 lvm2 a- 94.88G 0 /dev/sdb1 VolGroup00 lvm2 a-
