I have added a specification of probes for the fibre channel COMSTAR port provider to the DTrace section of wikis.sun.com. The proposal may be found here: http://wikis.sun.com/display/DTrace/fibre+channel+Provider I welcome feedback regarding this proposal. Thanks, Sam

I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people

For quite some time I?ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It?s time for me to replace my hardware and I have a new R720XD that I?d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I?m doing

We have a setup with 15 hosts fibre attached via a switch to a common SAN. Each host has a single fibre port, the SAN has two controllers each with two ports. The SAN is exposing four OCFS2 v1.4.2 volumes. While performing a failover test, we observed 8 hosts fence and 2 reboot _without_ fencing. The OCFS2 FAQ recommends a default disk heartbeat of 31 - 61 loops for multipath io users. Our initial

In principle, will Xen handle virtualization of Fibre Channel HBA''s? Say I have a physical server with a single FC HBA installed. If I create two domains, will XEN virtualize the HBA so that both of the domains can talk to the FC fabric? -M. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In waiting, I tried CentOS 8 which was an even bigger bust. I wiped that clean and tried again with Fedora 31. Same darn error "Could not create Target in configFS". Anyone??

Hi All, just a quick question I could not figure out. Is there a way to export a PCI device to multiple VMs (para) keeping it available to dom0? Xen version is 3.0.4.

I am wondering if any one knows of a way to manage Xyratex disk shelves from CentOS (in particular CentOS 4). More details: Some years ago I installed a NAS unit from Exanet which consists of 2 rebadged IBM x3650 head nodes and a couple of Xyratex disk shelves with a total of 96 TB of raw disk, connected by fibre channel. The operating system is based on CentOS 4.4, but is modified, and runs a

Hi, I''d like to test the stability of live migration during heavy load of domU. scenario: - both dom0s and domU are running on Debian Sarge. - script on dom0 triggers live-migration to the other dom0 - domU is running I/O tests, e.g. bonnie++ - domUs root- (ext3) and swap fs is stored on two partitions in a san - san is connected using fibre channel cards to both dom0s - san in dom0

Hello I''m a newbie here so please don''t laugh at me... I plan to setup several (4) physical servers to run xen virtualized OS-es (in example web servers). What I need is that those virtualized OS-es must have simultaneous access to disk storage physically created on FC array. I read that this could be done by OCFS or Lustre file system but my question is: how virtualized

Hello, I received the following question from a company I am working with: We are having issues with our early experiments with ZFS with volumes mounted from a 6130. Here is what we have and what we are seeing: T2000 (geronimo) on the fibre with a 6130. 6130 configured with UFS volumes mapped and mounted on several other hosts. it''s the only host using ZFS volume (only

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

CentOS 6.4 (amd64) stock kernel. HBA FC Accusys ACS 63200NT I built the driver from source, insmod activates the device and I can see the 24 TB storage volume via 'parted --list' I have created a XFS files system and mounted it under /srv/ Where do I need to install the driver in /lib/modules/ ... directory tree so that it is loaded automatically when the system boots? TIA, -- Arun

Please reply to david.curtis at sun.com ******** Background / configuration ************** zpool will not create a storage pool on fibre channel storage. I''m attached to an IBM SVC using the IBMsdd driver. I have no problem using SVM metadevices and UFS on these devices.

I had this exact same problem with 2.0.7. I had done a little investigation and found scheduled_work gets called to schedule the shutdown in the user domain kernel, but the shutdown work that gets scheduled never actually gets called. I''m glad someone else is seeing this same problem now :-) Like you, it worked a number of times in a row, then would fail, and it didn''t seem to

Hello again. Our production cluster has begun experiencing some vicious slowdowns that may (or may not) be related to the filesystems. When the problem occurs, the load average on the servers jumps up to 30 or higher. Usually one node will climb while the other drops, then they will switch places a few minutes later. At one point, we had one node's load average up over 300. Our site

Hi, I need to migrate about 8Tb of data from a Mac Fibre Channel RAID to by LVM Ext3 Linux Fibre Channel RAID. For speed I planned to connect both RAID's to my CentOS Server and copy the data directly. The Mac volume is formatted as Mac OS Extended (Journaled) it seems that CentOS 5.4 supports reading HFS volumes but not HFSPlus volumes. Is there a way of getting this volume to mount so I

Hi, I created an HVM type virtual machine and installed RHEL5U7 guest in it. I have assigned 7 scsi disks to the virtual machine in physical mode (using phy:), however, I see those disks are xvd and not as scsi. Is anyone aware what the problem might be ? Please let me know what kind of information do I need to post in order to narrow down to the problem. Thanks, K
