[Ocfs2-users] 答复: Fwd: Issue when I attempt to grow ocfs2 file system

[Guozhonghua]

The last parameter should be blocks-count, not size or capacity.  If the block size is 4k, you want extent to the capacity is 100G , the parameter should be 26214400.
26214400 = 1024*1024*1024 * 100 / 4096
Same time the disk size should be larger than the file system size you wanted.

You can use man tool to learn some about tunefs.ocfs2.
SYNOPSIS
       tunefs.ocfs2      [--cloned-volume[=new-label]      [--fs-fea鈁0m
       tures=list-of-features] [-J journal-options] [-L volume-label]
       [-N   number-of-node-slots]   [-Q  query-format]  [-ipqnSUvVy]
       [--backup-super] [--list-sparse] device  [blocks-count]

debugfs.ocfs can show the block size of the fs.
debugfs.ocfs2 -R "stats" /dev/dm-5 |grep Block\ Size

tunefs.ocfs2 -S /dev/sdx 100G,  means grow the fs to be 400G with block size 4k, but the disk is  100G, errors.

主题: [Ocfs2-users] Fwd: Issue when I attempt to grow ocfs2 file system

Hello list,

At this occasion I'm attempt grow my ocfs2 file system with the commands:

tunefs.ocfs2 -S /dev/sdx
tunefs.ocfs2 -S /dev/sdx 100G

The last command show me the following message:

"The ocfs2 filesystem on device "" cannot be larger than XXXX clusters (XXXX bytes)"

However, with the first command I can't grow it either. When I attempt do it, the prompt shell shows no outcomes. I've installed debian 9.0 and already have tried change the features but the issue continues.

Do you have any idea which may be the cause of issue ?

Regards.
