zfs failed to create special file

[RWDai]

unraid version 6.12.9

disk3:->zfs

 

When using docker's qbittorrent to download torrents, an error keeps reporting. Then I check the log and find that the file may not be created.

log:

(W) 2024-04-08T15:08:45 - File error alert. Torrent: "9月". File: "/download/manga/9月/2023-09-04/[コテ絵] プリヤ達が催眠術にかかったフリをしてロリコンキモデブ弱者男性粗ちん おじさんに 認知不要ラブラブ種付け孕ませレイプさせて受精する本 (Fate kaleid liner プリズマ☆イ.zip". Reason: "9月 file_open (/download/manga/9月/2023-09-04/[コテ絵] プリヤ達が 催眠術にかかったフリをしてロリコンキモデブ弱者男性粗ちんおじさんに 認知不要ラブラブ種付け孕ませレイプさせて受精する本 (Fate kaleid liner プリズマ☆イ.zip) error: Not supported"

So I tried to create the file directly in the directory, and found that the creation failed when the file system was zfs, but it could be created normally when the file system was xfs:

root@AIO:/mnt/disk3/data/download/manga/9月/2023-09-04# touch '[コテ絵] プリヤ達が催眠術にかかったフリをしてロリコンキモデブ弱者男性粗ちん おじさんに 認知不要ラブラブ種付け孕ませレイプさせて受精する本 (Fate kaleid liner プリズマイ.zip'
touch: cannot touch '[コテ絵] プリヤ達が催眠術にかかったフリをしてロリコンキモデブ弱者男性粗ちん おじさんに 認知不要ラブラブ種付け孕ませレイプさせて受精する本 (Fate kaleid liner プリズマイ.zip': Operation not supported

 

I have absolutely no idea why these files cannot be created on zfs, I have some examples as follows:

If anybody who are using zfs, can you use the example I provided to execute touch to see if you have the same problem?

I do see the same error, possibly zfs has more limitations on the file names it accepts.

If you want to make some tests, your example works for be if the pool is first created with -O normalization=formC -O utf8only=on, e.g.:

 

zpool create -f -o ashift=12 -O normalization=formC -O utf8only=on cache /dev/sdf1

 

Unfortunately this cannot be changed later, so the filesystem would need to be recreated manually, also not sure if it would cause other issue, but don't think so.

It's work，thank you！

I checked the github of zfs and found an issue with a similar problem.This problem has not been solved yet.The temporary solution is to set normalization to formC.

zfs issue 9965

I created a new dataset on unraid and tested successfully.

root@AIO:~# zfs create -o mountpoint=/mnt/disk1/test -o normalization=formC disk1/test
root@AIO:~# zfs list

Next, I will recommend to unraid developers to use this setting when creating a zfs shared directory.

OK, so just using formC solves the issue? I will report that to LT
