Hi there,
first off - sorry to bug you guys, relative simple issue - http://linux-iscsi.org/wiki/Support <- states to come here.
Anyways, walking my first steps with LIO, moving away from IET and running into an issue.
Rather than have several MD devices created out of partitions, we did the reverse. Added entire disks to MD and partitioned the MD set, resulting in device like /dev/md4p1, /dev/md4p2, etc.
Whilst these are block devices (afaik, seem to act that way everywhere else), targetcli doesn't seem to recognize them. At least not on the Ubuntu 12.04 server I'm trying it with, frequently giving not so savvy errors:
/backstores/fileio> create tt /dev/md4p1 For fileio, you must either specify both a file and a size, or just a device path.
Can't create it, did specify a path (more accurate error would be nice)
/backstores/fileio> create tt /dev/md4 Generating a wwn serial. Not using buffered mode. Created fileio tt with size None. Entering new node /backstores/fileio/tt No such path /backstores/fileio/tt
Creates it, but does give a no such path error, can cd into it and get status just fine....
/backstores/fileio> ls o- fileio ................................................... [1 Storage Object] o- tt ................................................. [/dev/md4 deactivated] /backstores/fileio> cd tt /backstores/fileio/tt> ls o- tt ................................................... [/dev/md4 deactivated] /backstores/fileio/tt> status Status for /backstores/fileio/tt: /dev/md4 deactivated /backstores/fileio/tt> cd ..
/backstores/fileio> delete tt Deleted storage object tt.
Deletes fine.
/backstores/fileio> cd ../iblock /backstores/iblock> create tt /dev/md4p1 Generating a wwn serial. Device is not a TYPE_DISK block device.
Same issue here as blockio.
/backstores/iblock> create tt /dev/md4 Generating a wwn serial. Created iblock storage object tt using /dev/md4. Entering new node /backstores/iblock/tt No such path /backstores/iblock/tt
Just like fileio creates it, but states no such path... Again can CD into it and get status tho'.
/backstores/iblock> cd tt /backstores/iblock/tt> status Status for /backstores/iblock/tt: /dev/md4 deactivated /backstores/iblock/tt> cd .. /backstores/iblock> delete tt Deleted storage object tt.
Thanks in advance :).
