My Vu+ Ultimo being able to play back recordings/timeshift without glitches/freezers that are not within the file (Rewinding helps, but is just a very bad workaround).

You can't blame the filesystem for that.

Sounds like a bug that was in the early drivers, are you using an old image or did that bug make a come-back lately?

[MiLo]

sure that the kernel module now added into the kernel directly?

No, it isn't, you'll have to install "kernel-module-xfs" first. And maybe modprobe it too.

It was gone in late august, after I did a complete re-install and formatted the HDD as ext3.
It returned a while ago, but as I could find out the file-system mutated to ext4 again in between...

The problem is even selective: The old recording, made resp. being copied back from backup while the file-system was still ext3, play without problems while the new ones play back like crap again.

So if the problem is not related to ext4 being a pile of junk I'm the emperor of China.

modprobe should not be necessary, I've added an autoload entry for the xfs module.

But indeed, if mount says 'unknown filesystem', you probably did not install the xfs module.
Check 'cat /proc/filesystems' to make sure xfs is listed.

Ni Hao,

In that case, you should make your case on Linux forum, not on a settopbox forum.

BTW: The mounting is not fail-safe.
After formatting my HDD as xfs, the box doesn't come up anymore.
Probably it's trying to mount the HDD and fails ... which is ok in theory, but it should give up some day ...
Mounting an optional volume should not result in the system to fail booting.

You really mean the box does not boot, or just that e2 fails to start?

It starts, but gets stuck at the small logo (Before the box even gets an IP or can be telnetted to).

[SpaceRat]

Is there any way to get the system up and running (telnettable) from USB stick only?
Else I would have to physically remove the harddisk and format it to something else on a PC ...

[SpaceRat]

Solved the problem:
1. Power Down Vu+ Ultimo
2. Open case
3. Unplug the HDD
4. Power Up Vu+ Ultimo
5. Telnet to box
6. opkg remove *xfs*
7. opkg remove linux-util-mount
8. opkg remove linux-util-umount
9. Power Down box
10. Re-Attach HDD
11. Power Up
12. Format HDD as ext3

So without the xfs packages, the box comes up ...

Ok this was a misunderstanding, now it works (modprobe wasn´t neccesary)

I have a problem mounting xfs formatted disk:

Formatting sda1 - xfs

mkfs.xfs /dev/sda1

-> works

Reboot - blkid:

/dev/ubi0_0: UUID="6cd013d7-b9bc-44dc-9c0a-54865a4bfd98" TYPE="ubifs"
/dev/sda1: UUID="0af3dbc7-4c3c-447d-a13f-62ce9b3a3295" TYPE="xfs"
/dev/sdb1: LABEL="STICKIE" UUID="28CE5C40CE5C0908" TYPE="ntfs"

-> disk shows up - xfs

but mount says:

rootfs on / type rootfs (rw)
ubi0:rootfs on / type ubifs (rw,relatime)
devtmpfs on /dev type devtmpfs (rw,relatime,size=145660k,nr_inodes=36415,mode=755)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
tmpfs on /media type tmpfs (rw,relatime,size=64k)
/dev/sdb1 on /media/STICKIE type fuseblk (rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
tmpfs on /var/volatile type tmpfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620)

-> sda1 did not mount

Mounting manually:

mount /dev/sda1 /media/hdd

NTFS signature is missing.
Failed to mount '/dev/sda1': Invalid argument
The device '/dev/sda1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

After doing that (without reboot) mount says:

rootfs on / type rootfs (rw)
ubi0:rootfs on / type ubifs (rw,relatime)
devtmpfs on /dev type devtmpfs (rw,relatime,size=145660k,nr_inodes=36415,mode=755)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
tmpfs on /media type tmpfs (rw,relatime,size=64k)
/dev/sdb1 on /media/STICKIE type fuseblk (rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
tmpfs on /var/volatile type tmpfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620)
/dev/sda1 on /media/hdd type xfs (rw,relatime,attr2,noquota)
[email="root@et9x00"]root@et9x00[/email]:~#

-> xfs disk shows up - media/hdd

funny, isn't it?
Newest PLI3.
What am I doing wrong?

like milo says, maybe you´ve got a hardware issue.
I thought the xfs modul is build directly into the kernel (like any regular distribution has, or dmm decided to do) but pli team decided to let its modular (like the most driver stuff).
so lsmod should bring you something like this:

root@et9x00:~# lsmod | grep xfs
xfs 594003 1
exportfs 3992 1 xfs

than the kernel loaded the xfs module correctly.
guess its more noob friendly to make the partition over the e2 GUI, and overwrighting the ext4 filesystem after this, than do the partition stuff with fdisk/sfdisk

[Martin_B]

Manually mounting xfs formatted disk:

mount /dev/sda1 /media/hdd -t xfs
-> works

mount /dev/sda1 /media/hdd
-> error as described above

[adri]

I have reformatted my 1 TB HDD with Xfs and am quite pleased with the results.
When pressing the PVR button, I often had to wait 3-5 seconds before the list of movies showed when the HHD was ext4.
Now it's showing in less than 1 second.
Also seeking and deleteing seems to be faster.

The only problem I have found is PLI doens't mount the HDD automatically anymore.
I had to add it manually to /etc/fstab.
This allowed me to add some extra performance options like noatime, nodiratime and allocsize.

Adri.

[hypnotoad]

I set the label flag when i formate, and wtih this flag it gets automatically mountet in /media/<label>
But something is realy strange, if i try to mount the hdd with fstab to any onter place, it doesn´t work, it allways gets to /media/<label>
Mounting by hand works like it should, it doesnt matter where the mountpoint is.
Mounting Network shares (nfs) in the fstab is no problem i can mount them anywhere.
But i guess all this is not xfs related, but nice to see that you have a better prefomance

No xfs kernel module for OpenPLi 4.0?

:-(

[MiLo]

opkg install kernel-module-xfs

[word]

Hello MiLo,

 

could you please provide it? Or where can i download it?

 

It is not available for Vu+ Duo2 in the feed.

 

Thanks and best regards
