Bug#815425: linux-image-3.16.0-4-amd64: cifs kernel lockup with rsync
Package: src:linux
Version: 3.16.7-ckt20-1+deb8u3
Severity: normal
I have a cifs mount from the NAS monitored by the inotify (minidlna
software). Usually files are transferred using the 'cp' utility. Once I invoked
rsync to copy files from the ext3 filesystem to the cifs mount. Then rsync
hanged with a following kernel message, mount.cifs and sync also hanged.
Dont's sure is it only rsync's fault because I interrupted a copy
operation before the faulty rsync invocation. Other machines can mount this
volume succesfully. Restarting samba on the NAS helped to umount a share
but subsequent remount hanged.
fstab entry:
//srv/movies /mnt/movies cifs defaults,credentials=/etc/samba.cred,iocharset=utf8,uid=irix,gid=users,file_mode=0775,dir_mode=0775 0 0
