Bug#1068733: lvm2: resize lv error "/usr/libexec/lvresize_fs_helper: execvp failed"

[antonio]

Package: lvm2
Version: 2.03.22-1+b1
Severity: normal
X-Debbugs-Cc: ***@gmail.com

Dear Maintainer,
when I resize a logical volume I get this error:

$ lvreduce --resizefs --size -5G /dev/system/test
File system ext4 found on system/test.
File system size (80,00 GiB) is larger than the requested size (76,00 GiB).
File system reduce is required using resize2fs.
File system fsck will be run before reduce.
Reducing file system ext4 to 76,00 GiB (81604378624 bytes) on system/test...
/usr/libexec/lvresize_fs_helper: execvp failed: File o directory non
esistente
Failed to reduce file system with lvresize_fs_helper.


this issue is noted here:
https://github.com/lvmteam/lvm2/issues/124
https://github.com/lvmteam/lvm2/blob/main/scripts/lvresize_fs_helper.sh


because file missing:
/usr/libexec/lvresize_fs_helper


I solved it by downloading the file:

sudo wget
https://raw.githubusercontent.com/lvmteam/lvm2/main/scripts/lvresize_fs_helper.sh
-O /usr/libexec/lvresize_fs_helper

sudo chmod +x /usr/libexec/lvresize_fs_helper


can you include this file in the package?


Thanks,
Antonio

Hello,
I just encountered this as well. I tried to check which package
contains "lvresize_fs_helper", but I could not locate it.

Later I read this bug, but I I think downloading a random file of
the internet before program execution (as root!) is not the "Debian
way", but this is even more so severe when you are in the middle of
a file system operation where e.g. the central partitions might not
be available, e.g. /home (so you cannot start the browser to search
for this file online).

The alternative is to do the steps manually:

***@twentytwo:~# resize2fs /dev/datavg/media
resize2fs 1.47.1 (20-May-2024)
Please run 'e2fsck -f /dev/datavg/media' first.

***@twentytwo:~# e2fsck -f /dev/datavg/media

Dear maintainer,

I've prepared an NMU for lvm2 (versioned as 2.03.27-1.1) and
uploaded it to DELAYED/10. Please feel free to tell me if I
should delay it longer.

Regards.
