[排错] Linux 解决使用 setfacl 命令时报错 “setfacl: …… : Operation not supported”

报错命令

# setfacl ......

报错代码

setfacl: ......: Operation not supported

解决方法

添加 acl 参数

临时解决方法(临时在挂载时添加 acl 参数):

# mount -o remount,acl /mnt

(补充:这里以给挂载的 /mnt 目录添加 acl 参数为例)

永久解决方法(永久在挂载时添加 acl 参数):

# vi /etc/fstab

将部分内容修改如下:

......
/dev/sda5 /mnt xfs defaults,acl 0 0
......

(补充:这里以给从硬盘 /dev/sda5 挂载到 /mnt 目录的目录添加 acl 参数为例)

[STEP] Limitation of the amount of the file which can be opened by Linux program

Step One: In system level, set the limitation of the amount of the files which can be opened by the user who running the Linux Program

# vi /etc/security/limites.conf

Add these lines:

......
rmt  -       nofile  1024
rmt  -       nproc   1024

(Add: Setting the rmt user can open 8192 files and 8192 processes in this Linux as an example here)

Step Two: In program level, check the setting of the amount of the files which can be opened by Linux program

# /bin/systemctl show 'rmt-server-mirror.service' | sort
......
LimitNOFILE=524288
......

(Add: The amount of opening the file by program rmt-server-mirror.service is limited at 8096 as an example here)
