‘lxc_cgfs – Perangkat atau sumber daya sibuk – gagal menyetel memory.use_hierarchy ke 1; melanjutkan' – kesalahan saat memulai wadah LXC

Masalahnya

Saat memulai lxc itu memberikan kesalahan di bawah ini:

lxc-start 1491315722.354 ERROR lxc_cgfs - Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start 1491315722.354 ERROR lxc_cgfs - Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start 1497957841.930 ERROR lxc_cgfs - Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start 1497957841.937 ERROR lxc_cgfs - Device or resource busy - failed to set memory.use_hierarchy to 1; continuing

Solusinya

Mempertimbangkan skenario di mana kita mendapatkan Error:Device or resource busy – failed to set memory.use_hierarchy to 1; melanjutkan:

# lxc-start --name CentOS7
lxc-start: cgfs.c: handle_cgroup_settings: 2077 Device or resource busy - failed to set memory.use_hierarchy to 1; continuing

Parameter /cgroup/memory/memory.use_hierarchy diatur ke 0 menyebabkan masalah. Gunakan perintah di bawah ini untuk memeriksa nilai parameter saat ini.

# cat /proc/mounts | grep -i mem
cgroup /cgroup/memory cgroup rw,relatime,memory 0 0

# ls /cgroup/memory/memory.use_hierarchy
/cgroup/memory/memory.use_hierarchy

# cat /cgroup/memory/memory.use_hierarchy
0

Jika kami mencoba untuk menetapkan nilai ke 1, itu masih menghasilkan kesalahan yang sama:

# echo 1 > /cgroup/memory/memory.use_hierarchy
-bash: echo: write error: Device or resource busy

Untuk menghilangkan Error :Device or resource busy – failed to set memory.use_hierarchy to 1; melanjutkan kita perlu mengikuti langkah-langkah di bawah ini:

1. Hentikan wadahnya
2. Hentikan layanan cgconfig
3. Mulai layanan cgconfig
4. Setel parameter /cgroup/memory/memory.use_hierarchy ke 1
5. Mulai penampung

# lxc-stop --name CentOS7

# /etc/init.d/cgconfig stop
Stopping cgconfig service: [ OK ]

# cat /proc/mounts | grep -i mem
#

# /etc/init.d/cgconfig start
Starting cgconfig service: [ OK ]

# cat /cgroup/memory/memory.use_hierarchy
0
# echo 1 > /cgroup/memory/memory.use_hierarchy
# cat /cgroup/memory/memory.use_hierarchy
1
