This is just an initial version of the patch, not to be applied. It implements just the diskgroup functions, ie. corresponding to these ldmtool commands: * ldmtool scan * ldmtool show diskgroup <guid> I have chosen yajl as the JSON parsing library (don't worry, this is optional). You will also, of course, need ldmtool which is not packaged in anything except Fedora. Rich.

When the LDM code was converted to the CLEANUP_* macros, a free() invocation for a CLEANUP_FREE variable was left in the ldmtool_diskgroup_volumes implementation, causing double-free on success.

We are looking at the alternatives to VXVM/VXFS. One of the feature which we liked in Veritas, apart from the obvious ones is the ability to call the disks by name and group them in to a disk group. Especially in SAN based environment where the disks may be shared by multiple machines, it is very easy to manage them by disk group names rather than cxtxdx numbers. Does zfs offer such

If we want to permit more than 255 drives to be added, then we will have to add the disks to the same virtio-scsi target using different unit (LUN) numbers. Unfortunately SCSI LUN enumeration in the Linux is not deterministic (eg. two disks with target=0, lun=[0,1] can be enumerated as /dev/sda or /dev/sdb randomly). Dealing with that will require some very complex device name translation on the

This is a simpler patch that removes GUESTFSD_EXT_CMD completely.

Replace GUESTFSD_EXT_CMD with a command line option ‘./guestfsd --print-external-commands’

The non- deterministic case is well known in other self-describing pools or diskgroups (eg: vxdg) and where the 6385531 RFE/bug came from on Leadville to provide more options for sites that lack flexibility on the SAN and presentation ports to mask out replicated disks.

Hi. I''d like to request a feature be added to zfs. Currently, on SAN attached disk, zpool shows up with a big WWN for the disk. If ZFS (or the zpool command, in particular) had a text field for arbitrary information, it would be possible to add something that would indicate what LUN on what array the disk in question might be. This would make troubleshooting and general

v2: wrap commit message, "PATCH libldm" prefix. v3: correctly initialize and free GLib resources. v4: gtk-doc is updated to reflect presence of new volume GUID field. The result of this patch might be used by libguestfs to return drive mappings for LDM volumes. Note, that "show volume" ldmtool command already returns hint which is a drive letter assigned by Windows to

Does anyone know what program can be used to query the RAID status from the OS for an on-board LSI SAS 2308-4i? On this page: http://docs.avagotech.com/docs/12351997 there is a curious note on the left that reads: "Integrated MegaRAID support available upon request" After one mostly fruitless round of chatting with LSI/Avago/Broadcom and one completely fruitless round of chatting
