PVR NW Share w/o USB or small image mod vusb.init

Post by DEUS » Thu Apr 12, 2012 8:31 pm

Please correct me if i am wrong but as far as i read in threads, Recording to NW Share without USB-Stick Connected, is not possible? (explanation will follow)
and there is also a neccesary size for the recording point arround 1,5 GB and has to be XFS (these restrictions are removed by widget)
there is nothing like iscsi or usbremote that can be mounted as a recording store. Basicaly there is no limit for the VirtualUSB exept aviable space? can it be 20MB? or should i expect any problems with a file big like this?

Got a file 16 MB size with an 1.6 GB xfs partition that works with g_file_storage and is possible to record on
dd if=/dev/zero of=XFSIMAGE bs=1M count=18 #This will be the container for the PVR Image Needs to be 18MB for formating
mkfs.xfs XFSIMAGE #Format with a FS that Supports Sparsefile
dd if=/dev/zero of=PVRIMAGE bs=1M count=1 seek=1536 #Create a Sparsefile (12 MB after formatting)
dd if=/dev/zero of=PVRIMAGE bs=1 count=1 seek=1536000000 #Create a Sparsefile smallest size (11 MB after formatting)
mkfs.xfs PVRIMAGE -L PVRIMAGE #Formats it with XFS for recording
modprobe g_file_storage file=PVRIMAGE #load as VUSB

here is a mod of remi71 init script which works on my TV with the record to NW share from remi71 would some of the Devs leave a comment about possible trouble from my point its only that it will consume 17MB space
02_04_vusb.vpvrimage.init

Script in 1. post updated, removed sleep because reformating takes also time, this also prevents FS coruption issues, another posibility is maybe to mount ro instead of rw needs to be tested, works with standard 03_03_nfsmount.init and 80_80_record_to_nwshare.init from remi71, on my TV

PVR NW Share w/o USB or small image mod vusb.init

Post by Rohel » Tue Apr 24, 2012 6:06 pm

I have to look If i can do it
If i understand what You have done Is a mod of one init script
But, How do you do to create the xfs file? Another init script??

it gets created every time you boot with
dd if=/dev/zero of="$PVRIMAGE" bs=1M count=1 seek=1536 status=noxfer 2>/dev/null
and then formated with xfs
but you need to disable $SYSROOT/etc/init.d/02_04_vusb.init
and configure remis 03_03_nfsmount.init and 80_80_record_to_nwshare.init
if you use this keep an eye on this thread

it seems that its working properly on my TV too, but im not able to mount the NFS
maybe its because im using a Mac laptop instead of a true NAS...

do you have replaced the rcSGO file like on remi's mod????

this is the log i found, and i have lost sammy virtual USB when i applyed your vusb.init

19700101-000020 Start Record to Network Share script (80_80_record_to_nwshare.init)
19700101-000020 Check if server 192.168.0.11 is reachable and NFS service available... OK
19700101-000020 Search for mount point of pvrimage...
19700101-000045 No virtual device found ready for PVR or already mounted
19700101-000045 End Record to Network Share script (80_80_record_to_nwshare.init)

if i exec vusb.init without a pen drive attached i see this in the web-cgi

Code: Select all

/mtd_rwcommon/widgets/user/SamyGO/SamyGO/etc/init.d/02_04_vusb.init start stop
Status:
cat: can't open '/sys/block/sd?/device/model': No such file or directory
if i do that with a pen attached, i see the name of the pen drive

Code: Select all

/mtd_rwcommon/widgets/user/SamyGO/SamyGO/etc/init.d/02_04_vusb.init start stop
Status:

NFS Mount seems to be ok

oh sorry lets do some clear instructions, take the code from 1. post create a file in samygo dir/etc/init.d/ called "02_04_vusb.vpvrimage.init"
rename 02_04_vusb.init to 02_04_vusb.init.dis, 03_03_nfsmount.init needs to be there and 80_80_record_to_nwshare.init from remi71 should be there (just rename it) and configure it, thats it when tv boots you should have 2 Virtual USB and on one you are able to record

ok now i have two shares on my TV, one for recording and other for everything else
seems to be OK, but i have to test to connect the computer without wifi to ensure tu pass performance test

or, are there any way to bypass performance test?

this doesnt work
i have created that file on the NFS Record root, and also in a folder called CONTENTS
maybe i have to create that file on the XFS image mounted on the script???
