In Topic: Unable to write files bigger than 2gb on cifs share.

Maybe someone else wants to test it.

I do :)

I think you should start by removing all those options, apart from vers, sec, username and password.

 

Chances are you get this (i admit very weird) error because of a non-supported option.

 

I am using minimal mount command:

mount -t cifs -o rw,username=username,domain=FSERVER,addr=192.168.0.61,vers=3.0 //192.168.0.61/dreambox /media/net/dreamboxFSERVER

which results to:

//192.168.0.61/dreambox on /media/net/dreamboxFSERVER type cifs (rw,relatime,vers=3.0,sec=ntlmssp,cache=strict,unc=\\192.168.0.61\dreambox,username=username,domain=FSERVER,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.61,file_mode=0755,dir_mode=0755,nounix,serverino,rsize=65536,wsize=65536,actimeo=1)

when i run mount command. 

Results is the same that AutoMount does, except relatime,vers=2.1 and nobrl option is missing.

 

When I have more time I will flash older openpli releases starting from 4.0 or maybe 6.2, because I have saved videos bigger than 2GB in my recordings directory from previous years. It was working before.

Tried that. smbfs is not recognized fs. I swapped it with cifs, but lfs is not recognized. This was the first option that I tried 2 days ago anyway.

I don't have smbclient on my xtrend at all.

mount: /media/net/dreamboxFSERVER: unknown filesystem type 'smbfs'.

mount -t cifs -o rw,noatime,vers=3.0,sec=ntlmssp,cache=strict,username=username,domain=FSERVER,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.61,file_mode=0755,dir_mode=0755,nounix,serverino,nobrl,rsize=65536,wsize=65536,actimeo=1,lfs //192.168.0.61/dreambox /media/net/dreamboxFSERVER
mount: /media/net/dreamboxFSERVER: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.

Your xtrend et6000 is built with a kernel 3.8.7.
Version 3 was not yet integrated there.
The use of version 3 does not bring any advantages.

Ok, I don't want SMB3 anyway. I tried because I red somewhere that version 2.1 had that 2GB limit. 

Just for the record:

mount command returns vers=3.0. 

It actually connects with SMB3_00 protocol. Also checked on file server host with smbstatus:

192.168.0.30 is the xtrend

I did a lot of tests:

root@et6x00:/# mount -t cifs -o rw,noatime,vers=2.1,sec=ntlmssp,cache=strict,username=username,domain=FSERVER,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.61,file_mode=0755,dir_mode=0755,nounix,serverino,nobrl,rsize=65536,wsize=65536,actimeo=1 //192.168.0.61/dreambox /media/net/dreamboxFSERVER
root@et6x00:/# dd if=/dev/zero of=/media/net/dreamboxFSERVER/output.img count=2048 bs=1048576
dd: error writing '/media/net/dreamboxFSERVER/output.img': File too large
2048+0 records in
2047+0 records out
2147483647 bytes (2.0GB) copied, 173.188893 seconds, 11.8MB/s

also tried vers=3.0 and vers=3.1.1 

vers=3.0 is recognized, anything else falls back to vers=2.1.

 

i also tried from another virtual machine which is debian testing like the file-server host (using the same mount options except noatime(which is not recognzied)). 

root@rtorrent:/mnt# umount /mnt/tmp; mount -t cifs -o rw,vers=2.1,sec=ntlmssp,cache=strict,username=username,domain=FSERVER,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.61,file_mode=0755,dir_mode=0755,nounix,serverino,nobrl,rsize=65536,wsize=65536,actimeo=1 //192.168.0.61/dreambox /mnt/tmp/

vers=3.1.1 was recognized here, but i used 2.1 just for testing like it is on the xtrend itself.

Operation was successful.
 
 

Can you confirm that this works for you. I mean the dd part.

mount -t cifs -o rw,sec=ntlmssp,cache=strict,username=username,domain=FSERVER,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.61,file_mode=0755,dir_mode=0755,nounix,serverino,nobrl,rsize=65536,wsize=65536,actimeo=1,vers=3.0 //192.168.0.61/dreambox /media/net/dreamboxFSERVER
dd if=/dev/zero of=dreamboxFSERVER/output.img count=2048 bs=1048576
