if you do the steps i posted before again, the command to create it would be

Code: Select all

touch /tmp/xfs/.PlaceHolderDO-NOT-REMOVE
then check if existing

Code: Select all

ls -alR /tmp/xfs
and unmount pvrimage

Code: Select all

umount /dtv/usb/sda1/SamyGO/pvrimage
then check again (placeholder file should be gone as mountpoint is empty without mounted image)


after a reboot you should see in output of cat /proc/mounts

Code: Select all

...lots of mounts...
/dev/sdc /dtv/usb/sdc xfs rw,nouuid,noquota 0 0
(recorder mount)
Hello, I cough steps and get this, after reboot, I get that line actually, the problem is that I found the flash drive to mount pvrimage

Post by beatfreak » Mon Dec 03, 2012 7:30 pm

your placeholder file has gone the wrong location... and i told the wrong command to unmount :oops:
plug your pendrive to your pc and remove your pvrimage and .placeholder... from SamyGO folder
(there are directorys in your pvrimage that do not belong there, should be on nfs share...)


in this example i created a new xfs image on my nfs share and then copied it to pendrive...

Hi, well finally I have the recording by nfs running, today when I saw your post it's clear the problem I had, I thought that /. PlaceHolderDO-NOT-REMOVE, had to create it in the USB device, rather than the NFS share for the recording, I'm a little clumsy with linux, thanks to you I work recording, and have learned to handle me a little better, thank you very much for your time and your help, now try the decryption will try to see if I do best, greetings

Re: SamyGo Extension Pack modified for NFS recording

Post by beatfreak » Thu Dec 06, 2012 4:57 pm

Now a general question from me...

i noticed that it takes about 30 sec. to start timeshift (from buttonpress || to actually stopped tv playback...

normal recordings start immediately and are recorded properly

opening tv recordings in media-play takes up to 1minute until the first recording is displayed and up to 3 minutes until i can select another recording to play

encryption is disabled


and one more thing: (back to xfs_img@nfs_share)
this is my plan to do the trick without the need of modified modules

*move the nfs-insmod block

Code: Select all

	insmod $MOD_DIR/kernel/net/sunrpc/sunrpc.ko
	insmod $MOD_DIR/kernel/fs/lockd/lockd.ko
	insmod $MOD_DIR/kernel/fs/nfs_common/nfs_acl.ko
	insmod $MOD_DIR/kernel/fs/nfs/nfs.ko
from 03_03_nfsmount.remi71.init appended to the start section of 02_04_vusb.remi71.init

*and then do a hard nfs mount right before checking for pvrimage file in 02_04_vusb.remi71.init
so the script would look like

Code: Select all

#!/bin/sh
#

could this work or are there more dependencies for the nfs-modules?

if it works,
@remi71: would you consider to mod your script like this? (would get too complicated if we release the mod of a mod of a script...)

[EDIT:]
i recently checked my rcSGO output and noticed:

Code: Select all

nfs mounting works though.
I checked the downloaded files and the modules not found were not included, forgotten to add them to the archive or forgotten to remove them from the scripts?

And as we already speak about script modifications:

after i changed my switch (from smc wbr14g 4-port to cisco 2924 19" 24-port) i noticed that tv needs more time to obtain an ip-adress. so the nfs-mount scripts fail.
i'd like to add a loop that pings the server before going to the showmounts section...
i'll try to post a sketch of it but i'm not familiar with the scripting-style the samygo-scripts are written in...

1st problem: i have seen that you used wait=nn in the scripts to slow down things, but i don't know how to define if it should be sec or msec and in general for unix/linux the command is sleep, wait would do something different...?

Code: Select all

test_network()

          A=1
          while [ $A <= 30 ]
          do
                        ping $SERVER -c 1 -q
                        if [ (ping successful) ]
                              A=10
                        else
                              A=A+1

Hello! I am using raspberry pi as NFS server. The thing works, I have only one problem and that is how can i change mount point for HDD movies folder. Its mount it on :dtv/usb/sdd, but samygo folder for videos( white usb key logo) is on dtv/usb/sdc I think. Thanks! Will explain later, beacause wright now I am not at tv....

# 

with this modificated scripts the 1,5GB xfs image file can be stored on a nfs share and no additional space on usb-drive or tv-flash is needed
NFS Server is running W7x64 and Hanewin-NFS-service

cut here
[/hr]

just tested alternate method involving a ntfs image with compression enabled to place pvrimage in /mtd_rwcommon or usb-drive smaller than 1,5GB
ntfs-3g and fuse needed for this

had to change
order of init scripts vusb after fuse
place ntfs-3g mount of ntfsimage right after start in vusb script (we should create a own script for that later, maybe with unpacking it from gzip to /dtv/, then we should call the whole thing OnionPVR :mrgreen: ) tested, zipping/unzipping takes to long to justify the (significant) amount of saved space
disable size check of pvrimage (or use a different method to get filesize)

please test for yourself :)

regarding the size check: i changed

Code: Select all

		GFILESIZE=`du $PVRIMAGE |cut -f1`
		if [ $GFILESIZE -ge 1536000 ]; then  	
to

Code: Select all

		GFILESIZE=`ls -l $PVRIMAGE | sed -e "s/ \+ / /g" | cut -d' ' -f5`
		if [ $GFILESIZE -ge 1572864000 ]; then  	
as ls prints the theoretical size of our imagefile other than du which prints the used space (and parameter du -b isn't implemented yet)

and this is my mountscript

	if [ -e $IMG_NTFS ]; then

		ntfs-3g $IMG_NTFS $NTFS_MP
	else
		echo "ntfsmage $IMG_NTFS NOT found, so we won't have a compressed pvrimage available"

P.S. the attached image only works with newer version of ntfs-3g, see viewtopic.php?f=21&t=4985&p=54402#p54399
