Subject: [f2fs-dev] f2fs.resize makes errors in FS
Date: Fri, 19 Mar 2021 23:24:05 +0200 [thread overview]
Message-ID: <55a201bb-5314-d3c9-cb0c-6420c3aa9f57@beroal.in.ua> (raw)
Hi. I am trying to use a new function to reduce the size of an F2FS file
system. After resizing, `fsck.f2fs` gives a lot of errors. Here is a
shell script that creates and resizes a dummy file system:
```
#!/bin/sh
set -e
F=/tmp/img
D=/dev/loop0
M=/root/mnt/temp
dd bs=1M count=256 if=/dev/zero "of=$F"
losetup "$D" "$F"
mkfs.f2fs "$D"
fsck.f2fs "$D"
mount "$D" "$M"
dd bs=1M count=64
if=/mnt/data/external/misc/movie/Idiocracy.2006.WEB-DL.1080p-ylnian.mkv
of="${M}/a.mkv"
umount "$M"
resize.f2fs -s -t 262144 "$D"
fsck.f2fs "$D"
losetup -d "$D"
```
```
+ set -e
+ F=/tmp/img
+ D=/dev/loop0
