Hi all, Can anyone explain to me, or point me to any docs that explain how the following numbers map together? I have multiple LUNS exported to my HBA''s from multiple EMC arrays. zpool status, and /dev/dsk show device names like: c0t6006048000038794003753594D333837d0 ONLINE 0 0 0 c0t6006048000038794003753594D333838d0 ONLINE 0 0 0

...m attempting to mount these filesystems until the network has been enabled on the system). This device is not a network device (this a SAN not a NAS). To the OS it looks like a normal SCSI attached device, it's /dev/sdb. In the blade there is a HBA (Qlogic) card, and it's connected through FiberChannel. If I understand these terms correctly, it has nothing to do with the network. On 10/10/2015 04:20 PM, Eero Volotinen wrote: > Does it work usin netdev option? > > Eero > 10.10.2015 4.17 ip.

Hi I have an IBM blade with internal harddisks, in hardware RAID1. I've installed a CentOS 6 64bit on it, everything works just fine. After the installation, I've presented a vdisk to the blade from an external SAN (an HP EVA4000), connected through FiberChannel. I've partitioned the disk, formatted it and mounted it under /store, then added it to fstab. Everything was fine, until I rebooted. At boot I'm getting the following error for /store: Mounting local filesystems: mount: special device UUID=2a587e95-4a6c-4336-bb8b-f0d066905bc5 does not ex...

...the hosted > services are. of course, the really tricky problem is implementing an ISCSI storage infrastructure thats fully redundant and has no single point of failure. this requires the redundant storage controllers to have shared write-back cache, fully redundant networking, etc. The fiberchannel SAN folks had all this down pat 20 years ago, but at an astronomical price point. The more complex this stuff gets, the more points of potential failure you introduce. -- john r pierce, recycling bits in santa cruz

Hi there. We have just setup a mail server with storage in a EMC Clariion SAN with fiberchannel connections. We're using two HP Proliant servers sharing the mail filesystem with OCFS2. The mail filesystem has several big directories having the biggest one over 7000 user directories. Some of the users have over 4000 messages, using Maildir as mail layout. We are experiencing really hi...

I've setup the CentOS version of the RH Cluster Service on a pair of centos 4.4 i386 test boxes... wanting to do high availabilty stuff. its working, I've added a virtual IP and a fiberchannel hosted e3fs file system thhat either can mount, if I manually crash or reboot one, this IP and FS mount on the other, awesome. the servers are connected to the storage via a QLogic SANbox 5600 fiberswitch, and I've added a SANbox2 'fence device' to the cluster, with its IP and logi...

Here is something I am currently lokoing at, and wondering if you'd considered it or if anyone here has done it. I've got a bunch of existing hardware - really good IBM stuff that is all installed with CentOS (with a few exceptions). We want to move to virtualization, but

Hi, I tried to do live migration from machine A to B. After the migration, machine A still had the record of the VM, though the VM was not running any more. Also, if I shut down the VM on machine B, its record on B would be gone --- I could not see it using "xm list" anymore. However, I can still start the VM on machine A using "xm start". Looks like the migration just move

...AID controller card then there is simply no real RAID functionality and no LSI component in that server model. NEC engineers very solid and produces very reliable server hardware. Many components are industry standard, as the Intel chipsets and processors, OEM LSI RAID controller cards, Emulex FiberChannel HBAs, ... NEC does not do any strange modification like implementing LSI firmware into Intel chips. Though their motherboards are their own design and are manufactured in Japan. Regards Alexander

I was wondering if anyone here has experience with HP MSA60 with P400 and P800 controller. How reliable are they for a 24x7 shop? TIA

...er the network. And it seems obvious to me that I'd want a dedicated network for doing that. That part is easy. But based on some poking around on the openfiler site and in the forums, it looks to me like it might be possible to stick a fiber channel card into an openfiler system, and serve fiberchannel out to other systems? Is that right? Is anyone here doing this? This does tie back in to CentOS directly because most of my systems are CentOS, and I'd eventually like to migrate them in this direction, depending on what comes of my benchmarking thanks, -Alan -- ?Don't eat anything y...

Hello, I have a Rocks cluster based on Centos 5.2. Can this Centos version support a Storage Area Network? What kind of software do I need for installing and managing it? Regards, Panos Nastou Dpt of Mathematics Aegean University Samos Island Greece

How does one configure a fence device in the form of a NIC card in centos 5? Is the gnbd item relevant to this? I have posted the question to linux-cluster also, but they are much less active overall, -so if you have info, massively appreciated... -karl

Is there a command that will list the disks that the system currently has? The df and mount commands only display info about filesystems. Charles L.

...Everyone, Whenever purchasing hardware we make it an effort to validate OS, driver and now hypervisor compatibility. Being a low budget company, we really look for the best bang for the bug. Right now that happens to be: x3755 M3 brandishing the AMD SR5690 chipset. We plan on installing a QLogic fiberchannel and a graphics card that support PCI passthrough. Before doing anything we are seeking the communities experiences, advice and feedback. As far as I have been told we have IOMMU enabled BIOS, so that should be promising. Kind Regards, Nick.
