Problem solved.
Seems like I can’t set stripe_unit to a value larger than object_size.
I should increase object_size attribute before increasing stripe_unit attribute.
Hope this would help someone. :)

Hi,
I want to play around with my ceph.file.layout attributes such as stripe_unit
and object_size to see how it affected my Ceph FS performance.
However I’ve been unable to set any attribute with below error.
$ setfattr -n ceph.file.layout.stripe_unit -v 41943040 file1
setfattr: file1: Invalid argument
Using strace I can see it failed at something related to missing locale
language pack.
Any suggestion how to resolve this?
$ strace setfattr -n ceph.file.layout.stripe_unit -v 41943040 file
open("/usr/share/locale/en_HK/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT (No
such file or directory)
open("/usr/share/locale/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT (No such
file or directory)
open("/usr/share/locale-langpack/en_HK/LC_MESSAGES/libc.mo", O_RDONLY) = -1
ENOENT (No such file or directory)
open("/usr/share/locale-langpack/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT
(No such file or directory)
write(2, "setfattr: file: Invalid argument"..., 33setfattr: file: Invalid
argument
) = 33
exit_group(1) = ?
Many thanks,
Haiyang
