Bug #52425
closed"rbd unmap" misbehaves if the image name contains glob metacharacters
0%
Description
The operation process is as follows：
root@master:~# rbd create test-pool/[0.0.0.0] --size 50G
root@master:~# rbd map test-pool/[0.0.0.0]
rbd: sysfs write failed
RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable test-pool/[0.0.0.0] object-map fast-diff deep-flatten".
In some cases useful info is found in syslog - try "dmesg | tail".
rbd: map failed: (6) No such device or address
root@master:~# rbd feature disable test-pool/[0.0.0.0] object-map fast-diff deep-flatten
root@master:~# rbd map test-pool/[0.0.0.0]
/dev/rbd1
root@master:~# rbd showmapped
id pool namespace image snap device
1 test-pool [0.0.0.0] - /dev/rbd1
root@master:~# rbd unmap test-pool/[0.0.0.0]
rbd: test-pool/[0.0.0.0]: not a mapped image or snapshot
rbd: unmap failed: (22) Invalid argument

Sigh, this is because libudev uses fnmatch(3) for matching attributes, meaning that shell glob pattern matching is employed instead of literal string matching. And it doesn't seem to be mentioned in the libudev API documentation, only in udev(7) man page:
Most of the fields support shell glob pattern matching and alternate patterns.
