扩展超级块中的 lv 坏魔法数字

扩展超级块中的 lv 坏魔法数字

我使用以下方法将服务器上的卷扩展了 300 GB:

lvextend -l +76800 /dev/vg0/simax

lvdisplay
--- Logical volume ---
LV Path                /dev/vg0/simax
LV Name                simax
VG Name                vg0
LV UUID                v6LxAS-U08H-JfM4-gp34-oQTk-Dlv5-tmuLbs
LV Write Access        read/write
LV Creation host, time thor.tcpmiss.it, 2013-08-08 09:55:57 +0200
LV Status              available
# open                 1
LV Size                495.31 GiB
Current LE             126800
Segments               2
Allocation             inherit
Read ahead sectors     auto
- currently set to     256
Block device           253:8

但随后尝试调整 fs 的大小:

resize2fs /dev/vg0/simax
resize2fs 1.42.5 (29-Jul-2012)
resize2fs: Bad magic number in super-block while trying to open /dev/vg0/simax
Couldn't find valid filesystem superblock.

服务器运行的是 debian:

cat /proc/version
Linux version 3.16.0-0.bpo.4-amd64 ([email protected]) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.16.7-ckt11-1~bpo70+1 (2015-06-08)

我不知道具体该怎么做;这是 df 的输出:

df -Th
Filesystem                Type      Size  Used Avail Use% Mounted on

答案1

使用此命令 # xfs_growfs /dev/vg0/simax 。我猜你的文件系统是 xfs
