TASK ERROR

[TROYa]

I am using Proxmox 7.3-3. It also has pbs installed. The entire HDD sda1 is given for backups. Copying works fine, but when restoring a large number of files, an error occurs:

Starting download of file: drive-scsi0.img.fidx/part/5/base/ÐелеÑСÑÑой ÐÐÐ ÐÑÑ
reading file extraction stream failed - error reading a body from connection: unexpected EOF during chunk size line
TASK ERROR: file restore task failed: command '/usr/bin/proxmox-file-restore extract '--crypt-mode=none' vm/100/2022-12-02T20:05:00Z 'ZHJpdmUtc2NzaTAuaW1nLmZpZHgvcGFydC81L2Jhc2Uv0JLQtdC70LXRgdCh0YLRgNC+0Lkg0J7QntCeINCR0YPRhQ==' - --base64 1 --repository Backup@pbs@192.168.0.10:Backup' failed: exit code 1


while each time the archive is 1.4 GB, although it should be more than 4.5 GB. What could be the reason?


It's not about coding. I have a server with exactly the same settings and everything is fine there.

On the Internet, I found the answer to a very similar error:
BUGS
As noted in xattr(7), the VFS imposes a limit of 64 kB on the size of the extended attribute name list returned by listxattr(7). If
the total size of attribute names attached to a file exceeds this limit, it is no longer possible to retrieve the list of attribute
names.


I use zfs and apparently it also has some kind of limitation. In one of the folders I restore 606662 files. So it seems the xattrs of that file are too big to list, so we cannot back them up...

I am experiencing the same problem, is there any solution to this?

Hi!
yes, you can use the `--skip-e2big-xattr true` attribute when making a backup. f.e.:

proxmox-backup-client backup test.pxar:./test --skip-e2big-xattr true

Note that you will lose all the metadata of the file where the error occurs.

Hi @ggoller,
Thank you for your quick response. I am a Proxmox newbie and just discovered the proxmox backup cli tool, awesome!
However my task was to restore some files which got lost between different backups. What i did was to use the map cmd.
Mounting the two backup images with

loop_device1=$(proxmox-backup-client map vm/101/$backup_name drive-scsi2.img --repository BACKUP-STORAGE-WD-EXT 2>&1 | grep -o '/dev/loop[0-9]\+')
loop_device2=$(proxmox-backup-client map vm/101/$backup_name_next drive-scsi2.img --repository BACKUP-STORAGE-WD-EXT 2>&1 | grep -o '/dev/loop[0-9]\+')
# Mount the drives
mount ${loop_device1}p2 /mnt/backup
mount ${loop_device2}p2 /mnt/backup_next

And let rsync do its job iterating over a few backups
Thanks for your help
