Hi, Each time i try tou use vhost_net, i'm facing a kernel bug. I do a "modprobe vhost_net", and start guest whith vhost=on. Following is a trace with a kernel 2.6.37, but i had the same problem with 2.6.36 (cf https://lkml.org/lkml/2010/11/30/29). The bug only occurs whith vhost_net charged, so i don't know if this is a bug in kvm module code or in the vhost_net code. Feb

I'm told that we cannot do Multipath I/O on our iSCSI SAN on RHEL with 2 network cards. I could use 1 network card, but need an HBA. Is this true? Do I need an HBA, or can I do Multipath using 2 NICs? We're running RHEL 4 and CentOS 4 and 5 servers on this network. I have been reading through the device-mapper documentation, but I have not found anything (unless I'm not clear on

Hi. I'm looking at a qlogic qle2462 hba for my dl360 g5. The thread http://www.mail-archive.com/freebsd-stable@freebsd.org/msg99497.html mentions a deadlock when system is loaded. Has this issue been resolved? Are there other PCI Express hba's which are known to work with freebsd stable and dl360 g5? -- regards Claus When lenity and cruelty play for a kingdom, the gentler gamester is

Hello, I have been looking around all day and lot''s of things are being thrown at me such as npiv and vscsi and such. I have an HITACHI,DF600F SAN which goes via two switch fabrics and plugs in to the dual port Qlogic HBA on the server(s). I have 4 Dell 2950''s at current which are under-utilised. I want to buy new 2xR710 and consolidate these 4 servers to a single physical

Hi, We know that the Command Line Interfaces (CLIs) for configuring and managing Emulex and QLogic Fibre Channel HBAs are included in the XenServer Host. Now suppose I want to configure and manage these HBAs out-of-band, say from some other virtualized or non-virtualized host. Is it possible ? If yes, then how?

Does anyone have any good or bad driver/performance/stability experiences with either: LSI Logic LSIU320 Adaptec 29320ALP-R or (or other current boards using the same driver) in Opteron servers running RHEL 4 or CentOS 4, x86_64?

Hi list, I have the choice to use RHEL4 or Centos4.x on a Dell PowerEdge2850 who is linked to an AX100 storage system. My question is: does the QLA200 (the pci fiber channel card) driver will work on CentOS 4.1 . For now the card is listed like this on CentOS 4.1: --- #lspci 09:04.0 Fibre Channel: QLogic Corp.: Unknown device 6312 (rev 03) --- What kind of modification must/can I do to the

Hi Everyone I am looking at setting up a File Server that uses ISCSI storage. It is the first time I have done this, so I am wanting to get peoples thoughts on whether for CentOS systems you should use Hardware based ISCSI HBA's? If so do I need to be careful about what HBA I use ? Currently I am looking at purchasing a Dell System using Broadcom ethernet cards/ ISCSI HBA. From

Hi, I have a host which is connected to SAN via single Fibre channel HBA (qlogic). I have several LUNS assigned to this (sdc, sdd). I added another single port HBA to this host. I can now see two world wide names. Now the confusion is which world wide name does sdc and sdd is/was using. scsi_id -g -u -s /block/sdc only gives wwid but I need the wwn for sdc and sdd. Thanks Paras.

Hello, Any idea when Cisco UCS Firmware Package will be included in centos Patching ? I had planned for Ontab storage upgarde, hence needed this level firmware version on CentOS Any help and leads will help me to plan the upgrade. Thanks

Hi all, this patchset implements an emulation for the megaraid_sas HBA. It provides emulates an LSI MegaRAID SAS 8708EM2 HBA, ie presenting to the guest a virtual SCSI adapter. Internally it is using aio for read/write requests and either SG_IO or SCSI command emulation for everything else. The reason for choosing the megaraid_sas HBA and not, say, implementing a virtio scsi interface is

Does anyone have any experience with Emulex HBA cards (LP10000) using OCFS2, Linux AS4 U4 x86_64 AMD? I'm trying to find out whether this is a verified combination, if anyone has successfully used it. I have that hardware/sofware combination, and am experiencing stability/performance/panic/hang issues with OCFS2. -------------- next part -------------- An HTML attachment was scrubbed... URL:
