I routinely store and access images over nfs w/o a problem with
darktable-2.5.0~git290.56880c853-193
can you access the remote drive locally via a file manager, mc, ..., or a
browser?
I unplugged from the router and plugged to the local box - it is usb3
Seagate 3TB drive. formatted Ext4. No issues when I work locally - it
imported 4k images in about 20 min or so. I am suspecting it is either
because of SMB update from Ubuntu or my mounting options are not great (but
they used to work before). Even now - on big files I can get up to 55-60
MB/s. When DT reads - I can monitor the speed to be about 1MB/s then slows
to few hundred k and then it goes to almost zero (over period of few hours).
no, can you access the remote drive from your computer directly thru the
router. nfs://x.x.x.x/... or similar
If I go to Nautilus and "connect to server" smb://172.16.30.3/ - yes I can.
is that the address you have in dt? I use nfs instead of smb, but have
absolutely no problems with nfs except it is somewhat slower than local
drives.
I cannot use nfs:// because the router won't serve it - it is Netgear R7000
with default firmware. Normally I hard mount it from fstab because I had
issues before when I use nautilus. I believe they were related to gvfsd-fuse
- to my understanding - nautilus is using this. After I moved to hard mount
with CIFS and fstab - it worked well for several years - until the other day
- I returned from vacation and applied the updates and the extreme slow down
happen.
I am on openSUSE Tumbleweed, don't know the *butu's, but just opened dt to
a cifs wireless access drive and dt is displaying jpg's about 3 every 5
seconds. and my dt is the latest git experimental.
I tried again I modified a bit the mounting options
//172.16.30.3/t_drive /media/bojo/netgear1 cifs
credentials=/home/bojo/bin/.smbcredentials,iocharset=utf8,sec=ntlm,uid=1001,gid=1001
0 0
I removed all images in the folder and tried to re import them. It worked
well for around 14 min - there are about 4400 images in the folder. It
imported about 230 of them and then DT simply crashed.
perhaps you should file a bug report,
https://redmine.darktable.org/projects/darktable/issues/new and attach the
backtrace, /tmp/darktable_bt_######.txt. most days you can find then on
irc, #darktable and maybe #pixls.us
Now i am "Extremely" confused. After the last crash - I restarted DT and
re imported the folder (some images were already imported (230). The
total amount of time to import all 4400 images was 8h+ !!! (I am glad it
completed ok).
Most of the time - it would pop an image every 6-7 seconds. Some times
it stalls to 1 image per 70 seconds. I noticed that even in the best
times - it would never use more than 2.5 to 5 MB/s bandwidth on read.
After DT completed - I quit it and tried (did not touch any of the other
programs) and tried to copy images from the router to the hard drive.
I selected 5GB of images with the corresponding XML and it copied in 1
min 15 s. Nautilus was utilizing 72 MB/s - again - I have not touched
the mounting. I repeated the test with 20 GB of images and corresponding
XML and it took 4 min 30 s (approximately).
Why is DT taking so long to import over SMB while the connection
apparently can carry much higher speed? Is it strictly related to SMB or
NFS would behave the same? I cannot utilize NFS currently...

B
