similar to: what is "single spanned virtual disk" on RAID10????

We are currently running CentOS 5 update 4 on a Dell R910 server 16 cores/32 hyperthreaded with 64GB of memory. It is our main Oracle 11g DB server for one of our customers and is attached to an MD 3000 storage array. We are having a load averaging around 5 but see no swap in use, CPUs are pretty much idle and no I/O wait. We have Oracle dataguard turned on in transactional mode. I've checked

Hi, we have SunFire X4140 connected to Dell MD1220 SAS enclosure, single path, MPxIO disabled, via LSI SAS9200-8e HBA. Disks are visible with sas-addresses such as this in "zpool status" output: NAME STATE READ WRITE CKSUM cuve ONLINE 0 0 0 mirror-0 ONLINE 0 0 0

We're looking for tools to be used in monitoring the PERC H800 arrays on a set of database servers running CentOS 5.5. We've installed most of the OMSA (Dell monitoring) suite. Our current alerting is happening through SNMP, though it's a bit hit or miss (we apparently missed a couple of earlier predictive failure alerts on one drive). OMSA conflicts with mega-cli, though we may

Running CentOS 6.7, on an older HP DL580 G5. We've got a Dell 12-bay RAID box plugged into a PERC H800 (aka LSI Liberator) that we put in the HP, and that works fine. We've got a new RAID (a JetStor), and are trying to plug it in. The layout is that the Dell RAID is dual-pathed DAS. Each PERC has two DAS ports. We've got the Dell RAID in the top port of each PERC. I *thought* I could

We have several DELL servers with MD1000 connect to it. Server will install CENTOS 5.x X86_64 version. My questions are: 1. Which configuration have better performance RAID5, RAID50 or RAID60? 2. how much performance difference? ___________________________________________________ ??????? ? ???????????????? http://messenger.yahoo.com.tw/

I have tried sending this before, but it did not appear to get through. Hello, When using gfs2 with quotas on a SAN that is providing storage to two clustered systems running CentOS6.5, one of the systems can crash. This crash appears to be caused when a user tries to add something to a SAN disk when they have exceeded their quota on that disk. Sometimes a stack trace is produced in

we have DELL server (CENTOS 4.X) with MD1000 connect on it. One of Raid5 (internal 4 disks) has hard disk bad and I replace it.

Happy Friday, List! I''m spec''ing out a Thumper-esque solution and having trouble finding my favorite Hitachi Ultrastar 2TB drives at a reasonable post-flood price. The Seagate Constellations seem pretty reasonable given the market circumstances but I don''t have any experience with them. Anybody using these in their ZFS systems and have you had good luck? Also, if

My apology for cross posting We have a DELL6850 with 8Gbytes of memory, four 3.2Ghz CPU's , perc 4 raid controller, with fourteen 300Gbyte 10Krpm disk on a powervault 220s, And a powervault 124T LTO-3 tape systems on a separate 160Mbyte/sec adaptec SCSI card.

I just created a 4 drive mdadm --level=raid10 on a centos 4.8-ish system here, and shortly thereafter remembreed I hadn't updated it in a while, so i ran yum update... while installing/updating stuff, got these errors: Installing: kernel ####################### [14/69] raid level raid10 (in /proc/mdstat) not recognized ...

Hi, I have Dell md1200 connected to two heads ( Dell R710 ). The heads have Perc H800 card and drives are configured in Raid0 ( Virtual Disk) in the RAID controller. One of the drives had crashed and is replaced by a spare. Resilvering was triggered but fails to complete due to drives going offline. I have to reboot the head ( R710) and drives comes online. This happened repeatedly when

I would like to set up CentOS on 4 SATA hard drives that I would like to configure in RAID10. I read somewhere that Raid10 support is in the latest kernel, but I can't seem to get anaconda to let me create it. I only see raid 0, 1, 5, and 6. Even when I tried to set up raid5 or raid1, it would not let me put the /boot partition on it, and I though that this was now possible. Is it

hi guys, gals do you know if conversion from lvm's raid10 to raid0 is possible? I'm fiddling with --splitmirrors but it gets me nowhere. On "takeover" subject man pages says: "..between striped/raid0 and raid10."" but no details, nowhere I could find documentation, nor a howto. many thanks, L.

we have DELL 6800 server with 12 internal disks in it. O.S. is CENTOS 4.6 and SCSI control card is PERC 4e/di. We plan to configure 4 disks (5,8,9,10) as RAID5 or RAID50. This logical volume will be use as file systems and store database backup files. Can anyone tell me which one is better on performance?
