== <s>Defrag on SSD</s> ==
The wiki currently recommends mount options for autodefrag [https://wiki.archlinux.org/index.php/Btrfs#Examples see here]; I thought defrag on SSDs was considered wasteful with no performance gains.  Am I mistaken? [[User:Graysky|Graysky]] ([[User talk:Graysky|talk]]) 11:07, 28 November 2013 (UTC)
:Hey Graysky, good point, but Btrfs seems to be a bit different in this regard (at least at present): [https://btrfs.wiki.kernel.org/index.php/Gotchas Btrfs Wiki Gotchas], [https://btrfs.wiki.kernel.org/index.php/Mount_options Btrfs Wiki Mount options], and [http://www.phoronix.com/scan.php?page=article&item=linux_btrfs_311&num=1 Phoronix 3.11 Benchmarking].
:Maybe after the bug mentioned in "Gotchas" is squashed it may not be necessary, but the developers mention adding autodefrag as a default in the future, and I am not clear whether or not this will be applied to both SSDs and HDDs. Further, noting the benchmarks from Phoronix, at worst autodefrag does not seem to have a performance hit on SSDs. If you have sources that indicate differently please let me know, but at present this is the best I have found. I will add a tentative note to the section in question in case others have similar questions. -- [[User:AdamT|AdamT]] ([[User_talk:AdamT|Talk]]) 19:27, 28 November 2013 (UTC)
==<s> Capitalization: "Btrfs" or "btrfs"? </s>==
[[Wikipedia:Btrfs|Wikipedia]] uses "Btrfs", whereas the [https://btrfs.wiki.kernel.org/index.php/Getting_started official wiki] uses both "Btrfs" and "btrfs" inconsistently. Sometimes there's even "BTRFS". What is the correct capitalization?
'''Edit:''' It seems that official man pages use "btrfs" consistently.

:: What should we follow for this article for consistency sake if nothing else? For what it is worth Chris Mason seemed to consistently use "Btrfs" circa-2008: [https://oss.oracle.com/~mason/] and [https://oss.oracle.com/~mason/blog/].

:::We can find plenty of supporting documents for both spellings, so basing our choice on that will never solve the problem, unless one day some bTrfS developer will state officially and explicitly what the correct spelling is. So, until then, let's just use "Btrfs" (capital B, all the rest lowercase): I hope everybody will peacefully agree. Now, we should probably state this "rule" permanently somewhere in this talk page, maybe in a note at the top? -- [[User:Kynikos|Kynikos]] ([[User talk:Kynikos|talk]]) 09:30, 6 January 2014 (UTC)

Revision as of 09:34, 12 January 2014

Note: The name of the file system does not seem to have an official capitalization, so the rule for the ArchWiki has been arbitrarily set to use "Btrfs" (capital "B" and the rest lower-case); "btrfs" and "BTRFS" are therefore wrong spellings in this wiki. -- Kynikos (talk) 09:36, 6 January 2014 (UTC)

Grub Partition Offset

I can confirm that btrfs can be installed without creating a 1 or 2 MB partition at the beginning of the disk using the latest December ISO.
