* rbd: fix cleanup when trying to mount inexistent imageYehuda Sadeh2011-01-121-4/+15
| | | | | | | | Previously we didn't clean up the sysfs entry that was just created. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
* rbd: replace the rbd sysfs interfaceYehuda Sadeh2010-12-011-277/+471
| | | | | | | | | | | The new interface creates directories per mapped image and under each it creates a subdir per available snapshot. This allows keeping a cleaner interface within the sysfs guidelines. The ABI documentation was updated too.

* rbd: passing wrong variable to bvec_kunmap_irq()Dan Carpenter2010-10-201-1/+1
| | | | | | | | | We should be passing "buf" here insead of "bv". This is tricky because it's not the same as kmap() and kunmap(). GCC does warn about it if you compile on i386 with CONFIG_HIGHMEM. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>
* rbd: null vs ERR_PTRDan Carpenter2010-10-201-2/+2
| | | | | | | ceph_alloc_page_vector() returns ERR_PTR(-ENOMEM) on errors. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>
* block: rbd: removing unnecessary testYehuda Sadeh2010-10-201-4/+0
| | | | | | | rbd_get_segment() can't return a negative value, we don't need to check the return output. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net>
* block: rbd: fixed may leaksVasiliy Kulikov2010-10-201-6/+8
| | | | | | | | | | rbd_client_create() doesn't free rbdc, this leads to many leaks. seg_len in rbd_do_op() is unsigned, so (seg_len < 0) makes no sense. Also if fixed check fails then seg_name is leaked. Signed-off-by: Vasiliy Kulikov <segooon@gmail.com> Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net>
* rbd: introduce rados block device (rbd), based on libcephYehuda Sadeh2010-10-201-0/+1843
The rados block device (rbd), based on osdblk, creates a block device that is backed by objects stored in the Ceph distributed object storage cluster. Each device consists of a single metadata object and data striped over many data objects. The rbd driver supports read-only snapshots.
