- Set the max number of counts before a filesystem is checked to 2:
|
|
|
|
|
|
|
|
|
|
`tune2fs -c {{2}} {{/dev/sdXN}}`
|
|
|
|
|
|
|
|
|
|
- Set the filesystem label to MY_LABEL:
|
|
|
|
|
|
|
|
|
|
`tune2fs -L {{'MY_LABEL'}} {{/dev/sdXN}}`
|
|
|
|
|
|
|
|
|
|
- Enable discard and user-specified extended attributes for a filesystem:
|
|
|
|
|
|
|
|
|
|
`tune2fs -o {{discard,user_xattr}} {{/dev/sdXN}}`
|
|
|
|
|
|
|
|
|
|
- Enable journaling for a filesystem:
