For complete info an all tools for btrfs please do an actual search at the arch wiki and at the manjaro forum for "btrfs". In the following section only a few commands are described. Especially those commands that are often misinterpreted. Commands described earlier are omitted. | |||
== | == btrfs (the command)== | ||
Be aware that some sub-commands of btrfs will not work as normal user. Other sub-commands do work but will give only partial info. So best use them as ''root'' or with ''sudo''. | |||
=== | ==== help, version ==== | ||
this is not what you think it is 😜 | '''help''' together with '''man btrfs''' or '''info btrfs''' will get you an overview over the usable options on your install. {{UserCmd|command=btrfs help}} | ||
With the '''version''' of btrfs given here you can look at [https://btrfs.wiki.kernel.org/index.php/Changelog changelog].{{UserCmd|command=btrfs version}} | |||
==== device ==== | |||
'''scan''' will give no visible results 😜 | |||
{{RootCmd|command=btrfs device scan}} | |||
'''stats''' will give a list of errors detected in the past. This all should be 0, or you may be in trouble. | |||
{{RootCmd|command=btrfs device stats /}} | |||
What to look for in device '''usage''': | |||
* RAID-level of Data, Metadata and System | |||
* Unalocated: | |||
Don't ever let ''Unalocated:'' get below 5% of your volume (or double the size you need for your next update)! If this goes too low, you will get into "out of space" trouble | |||
{{RootCmd|command=btrfs device usage /}} | |||
Without sudo this will give very wrong results for everything displayed. '''Dont´t use this without sudo !''' | |||
