- is the relevant CIFS collection added as a network collection or as a normal collection in setup? Is the directory sometimes not mounted? - is the command find /home/username/Bilder/net_bilder considerably faster than digikam's scanning? The relevant cifs-collection is added as a network collection in setup. The find /home/username/Bilder/net_bilder takes 00:02:36.69. Yes it is considerably faster. Even over night digikam is unable to start. I tried starting digikam without the cifs being mounted. Digikam starts immediately. Perhaps this cli output is helpful.

I switched to another Linux distribution. The reported Bug occured with Fedora 15. Now I'm using Ubuntu 11.04. Everything works fine and digikam starts within 4 minutes. In consideration of my collection's size (see above) this is acceptable for me. It is still slower than a local collection, and needs improvement, but as you see the major issue was due to CIFS implementation probably in connection with adding KDirWatches. |
Version: 1.9.0 (using KDE 4.6.3) OS: Linux Although the option 'Scan for new items on startup' is deactivated, digikam traverses the whole storage in /home/username/Bilder where in /home/username/Bilder/net_bilder a cifs is mounted. For each directory digikam calls inotify_add_watch (not included in the following strace). Each time the cifs is mounted digikam hangs on reading database with the following strace. This behaviour is reproducible. The image storage is located on a raid storage 1.5TB of size. The image storage's size is 77 GB with 195,033 files in 9,668 folders. All drives have more than 80GB of free space. The sqlite3 databse is located in /home/username/Bilder. /home/username/Bilder + net_bilder (cifs mount point) + digikam4.db + thumbnails-digikam.db 'strace digikam' produces the following output: [...]thousands of other lines[...] stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic13.jpg", {st_mode=S_IFREG|0755, st_size=65866, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic11.jpg", {st_mode=S_IFREG|0755, st_size=52490, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic14.jpg", {st_mode=S_IFREG|0755, st_size=61893, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic16.jpg", {st_mode=S_IFREG|0755, st_size=61375, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic06.jpg", {st_mode=S_IFREG|0755, st_size=44437, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic07.jpg", {st_mode=S_IFREG|0755, st_size=59157, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic09.jpg", {st_mode=S_IFREG|0755, st_size=72442, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic18.jpg", {st_mode=S_IFREG|0755, st_size=99327, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic10.jpg", {st_mode=S_IFREG|0755, st_size=66041, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic01.jpg", {st_mode=S_IFREG|0755, st_size=81829, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic15.jpg", {st_mode=S_IFREG|0755, st_size=64597, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic08.jpg", {st_mode=S_IFREG|0755, st_size=64902, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/.picasa.ini", {st_mode=S_IFREG|0755, st_size=320, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic03.jpg", {st_mode=S_IFREG|0755, st_size=85237, ...}) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic05.jpg", {st_mode=S_IFREG|0755, st_size=54018, ...}) = 0 getdents64(52, /* 0 entries */, 32768) = 0 close(52) = 0 stat64("/home/username/Bilder/net_bilder/cifs_mounted_here/pic12.jpg", {st_mode=S_IFREG|0755, st_size=66438, ...}) = 0 open("/etc/mtab", O_RDONLY) = 52 fstat64(52, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb788b000 read(52, "rootfs / rootfs rw 0 0\n/proc /pr"..., 1024) = 1024 read(52, "ct 0 0\ncgroup /sys/fs/cgroup/mem"..., 1024) = 1024 read(52, "latime,mode=755 0 0\n/dev/sda5 /b"..., 1024) = 1024 read(52, "6384,wsize=57344,actimeo=1 0 0\n/"..., 1024) = 274 read(52, "", 1024) = 0 close(52) = 0 munmap(0xb788b000, 4096) = 0 lstat64("/home", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 lstat64("/home/username", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 lstat64("/home/username/Bilder", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 lstat64("/home/username/Bilder/net_bilder", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0 lstat64("/home/username/Bilder/net_bilder/sway", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0 lstat64("/home/username/Bilder/net_bilder/cifs_mounted_here", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0 inotify_add_watch(21, "/home/username/Bilder/net_bilder/cifs_mounted_here", IN_MODIFY|IN_ATTRIB|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_DONT_FOLLOW) = -1 ENOSPC (No space left on device) inotify_add_watch(21, "/home/username/Bilder/net_bilder/cifs_mounted_here", IN_MODIFY|IN_ATTRIB|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_DONT_FOLLOW) = -1 ENOSPC (No space left on device) select(21, [20], NULL, NULL, {0, 0}) = 0 (Timeout) write(20, "A\0\1\0i\5\2\0007\0/home/username/Bilder/"..., 65) = ?

Here more information concerning my laptop. http://www.smolts.org/client/show_all/pub_8d14167e-db4d-40c9-99e4-ac63418ef8e3 I'm not using the KDE-Desktop. My desktop environment is Gnome3 with the gnome-shell. The current Kernel is 2.6.38.7-30. Reproducible: Always Steps to Reproduce: Start digikam with lagre image storage mounted by cifs. Actual Results: It hangs showing the splash screen with reading database message on it. Expected Results: Simply startup. Cause of digikam is unusable the severity will be set to crash.
