PartClone Error

[Xibeaga]

Hi Tom!

Ah, sdA is data, i boot from sdB:

sdb = ext4 = boot disk
sda = btrfs = data

so, the problem persists. Any idea about it?
Maybe BTRFS is the problem?

thx!

@xibeaga how do you know this? What’s output of fdisk -l

@tom-elliott

Here you can see the mount and fdisk output:

root@uhura:~# mount | grep “sd[a|b]”

/dev/sda1 on /harddisk type btrfs (rw,relatime,ssd,space_cache,subvolid=5,subvol=/)

@xibeaga as strange as it sounds is it likely a problem with partclonr, maybe even the version of partclone? Can you try clonezilla to see if it works out of the box. Note I’m not questioning your skills or anything, I just don’t see the full picture. That’s why I asked about fdisk. Otherwise it’s like saying I made a cake but it didn’t rise as expected. Why didn’t it rise? Probably no flour or not enough eggs, is yeast expected. But we don’t know because we only got a very small amount of information.

@tom-elliott
hey, no problem at all! :)))

Okay, ic. I suspected partclone too.

I never used clonezilla, I just know it exists. I use fog since 0.98 or so…
Ok, I will try clonezilla on this.
Hm, maybe i should try fog with dd first?

@tom-elliott
Okay, clonezille (live) crashed too.
it terminates without any error-message or exit-code.

the only solution I came up at the moment is:
running fog DEBUG and boot into a shell
then mount the fog nfs share
then dd both disks onto that share

so, at least i have a backup

if you have any better idea, you are welcome!

best regards,

Hi!

i just saw, that FOG uses partclone 0.2.89 but 0.3.10 is actual.
BTRFS seems to be an issue with partclone.

Is there a way to upgrade partclone to 0.3.10 in a debian installation of fog ?

thx!

[Tom Elliott]

@xibeaga partclone is built as a part of the inits. Last I got around to partclone 0.2.89 was the latest stable version. I can try updating it but if you said clonezilla had the same issue I suspect updating wouldn’t help anything.

@tom-elliott
I think i will change the FS of the disk, so it will become cloneable.

have a nice day and thanks a lot for your help!
can you mark the thread solved?

[Tom Elliott]

I’ve rebuild the init’s with Partclone v0.3.11 which is in the unstable directory. I have tested a linux based image with ext4 partition and that appears to not work properly yet. This appears to be a version issue (meaning something changed for ext4 application as reverting back to 0.2.89 with the same image file works fine). I don’t have an OS with btrfs so I will request you test this? I say this because from what I gather btrfs support was fixed in 0.3.10 from this pull request.

For the simple cause that ext4 imaging is broke, and I’m not sure on the status of XFS, NTFS, or BTRFS, I find it unlikely this new version will make it into 1.5.3. I don’t know when a new version of partclone will be available to test and build. Right now, 0.3.11 has no issues building, but ext filesystems are unable to be checked, like it’s putting the data on the wrong inodes. I don’t have a windows system to test with yet, so I’m not sure of the status of NTFS. I’m also unsure of XFS and BTRFS. Hopefully, however, at least capturing would work. As far as deploying, well that’s another issue.

The files can be downloaded using the linked names:

init.xz
init_32.xz
