Record PVR to NAS (NFS)

[Joejoe]

So, after many hours I have the scripts
- 02_04_vusb.init.remi71
- 03_03_nfsmount.init.remi71
- 80_80_record_to_nwshare.init.remi71
rewritten to work for me.

At this link http://wiki.samygo.tv/index.php5/PVR_Re ... r_C-Series I read:

NOTE: Although the media screen report that the SamyGo Virt. USB device for recording is 1.5GB, don't worry because the NFS share is remounted into the original mount point of the XFS image so the real size is the free space on your server.

What I have now found out is that first of all the nfs share is mounted. Then from the xfs file at the nfs share (in my case the ext4 file) is created a virtual-usb-device. Then on the mount-point of the virtual usb device (in my case /dtv/usb/sdb) the nfs-share is mounted on it again.

After running the nfsmount-script and the vusb-script i have a device that is in ext4 format with a size of 10GB (the size of my ext4 image-file) ~900Mb used on it. This device is still not able to save PVR on it because of the speed test. Now running the record_to_nwshare-script. Found the mount point and mount nfs-source i define in PVRPATH on /dtv/usb/sdb. Now my device is 10Gb of 10Gb full and still not able to save PVR on it.

I even try to umount the ext4 at /dtv/usb/sdb first and then mount nfs-source on it > same result.

What's my error?

first it will be the easiest to create a new xfs/ext4 image, it seems that the second nfs mount didn't work and the data has gone into your image instead of the nfs share.
did you put the

.PlaceHolderDO-NOT-REMOVE

file in your image? (don't forget the starting dot)
in 80_80 script we look for this file/flag to identify the pvr-image and mount the nfs-record-share there

EDIT: and do we really need 10GB on F-Series?

P.S.
as my nfs-server macine runs win7 i placed my pvr-xfs-image (1,5GB for C-Series TV) on a compressed ntfs partition, size on disk ~780KB

Here is the output of test.cgi when I start the record_to_nwshare-script:

It all seems to be fine. But the said error (10GB/10GB full) is anyway. Even if I try to record/timeshift the TV tell me that ther is sufficient capacity.

The 10GB-image-file is not the error I think. At first I thought the TV records into the image-file so I created it extra large.

ok, one more check:
-disable 80_80_record_to nwshare script
-reboot tv
-connect via telnet/ssh
-post output of

Code: Select all

ls -alR /dtv/usb/sdb

if sdb ist your mounted ext4 image

[Joejoe]

Here it is :

ok as you see there is definately more stuff in it that should be
i think you should create a new image to get a clean one
- disable vusb, nfsshare and record_to_nwshare scripts
- reboot
- connect via telnet/ssh
- create a folder in /dtv to have a mountpoint
- manually mount your nfs share there
- delete your old imagefile
- and create a new one following the steps in wiki (steps 10,11,12) you'll have to create an additional mountpoint for the new image
- unmount the new image and move it to the location mentioned in vusb script
- enable vusb and nfsshare scripts and reboot
- again do a ls -alrR /dtv/usb/sdb
and don't try to access pvr/timeshift menu while record_to_nwshare script is disabled ! (also turn off automatic timeshift mode before you begin with this all)

[Joejoe]

So, new ext4-file with file size only 1,5Gb.

Output of "ls -alR /dtv/usb/sdb" :

After enabling the 3 scripts the mountpoint is found and the record_to_nwshare-script was startet properly the same error appears. 1,5GB/1,5GB full and no way to PVR or timeshift

[beatfreak]

check output of

Code: Select all

cat /proc/mounts

for something like

Code: Select all

192.168.2.10:/recordshare /dtv/usb/sdb nfs rw,vers=3,rsize=32768....

with your matching ip adress and sharename of course

and its good to put any file on your NAS / NFS-share you wnt to record to, then when checking /dtv/usb/sdb for contents you immediately see if everything has been mounted correctly

[Joejoe]

I don't know if output of "cat /proc/mounts" seems to be good?

looks quite good

192.168.0.100:/volume1/Samsung-Aufnahme/ /dtv/usb/sdb nfs rw,noexec,relatime,vers=3,rsize=131072,wsize=131072,namlen=1020,soft,nolock,proto=tcp,port=65535,timeo=70,retrans=3,sec=sys,local_lock=all,addr=192.168.0.100 0 0

ext4 image is mounted on sdb and nfs share ist mounted over it, so you should see your contents of volume1/Samsung-Aufnahme when you do
ls /dtv/usb/sdb

P.S. if necessary german support via pn
