You have been subscribed to a public bug:
Using growpart with locale cs_CZ on RHEL7/RHEL8 encounters the following error,
# growpart /dev/xvda 2 -v -N
unexpected output in sfdisk --version [sfdisk z util-linux 2.23.2]
I found that,
when LANG=cs_CZ.UTF-8, run command "sfdisk --version" would get "sfdisk z
util-linux 2.32.1".
It is weird that the char between z and util-linux is not a space char but a
char of UTF-8 code 302.
$ set -- sfdisk z util-linux 2.32.1
$ echo $2
z util-linux
$ echo $2 |od -b
0000000 172 302 240 165 164 151 154 055 154 151 156 165 170 012
0000016
$ echo $3
2.32.1
$ echo $4
so the growpart command failed because the $4 is unset in this case.
# expected output: sfdisk from util-linux 2.25.2
out=$(sfdisk --version) ||
{ error "failed to get sfdisk version"; return 1; }
set -- $out
ver=$4
case "$ver" in
[0-9]*.[0-9]*.[0-9]|[0-9].[0-9]*)
IFS="."; set -- $ver; IFS="$oifs"
SFDISK_VERSION=$(($1*10000+$2*100+${3:-0}))
return 0;;
*) error "unexpected output in sfdisk --version [$out]"
return 1;;
esac
[Solution]
one simple fix for growpart could be adding LANG=C before the command sfdisk
--version, e.g.
out=$(LANG=C sfdisk --version) ||
