Kent Overstreet, utvecklare av filsystemet Bcachefs, har f\u00f6reslagit patchar som g\u00f6r det m\u00f6jligt f\u00f6r Linux-k\u00e4rnan att arbeta med Bcachefs \u00e4ven efter skador p\u00e5 betydande m\u00e4ngder metadata, genom att ombygga skadade b-tr\u00e4d fr\u00e5n metadata i inode- och dirent-strukturer. \u00c4ndringarna har godk\u00e4nts av Linus Torvalds och inkluderats i den aktuella testuppdateringen av k\u00e4rnan 6.9-rc3. <\/p>\n

\u00c4ndringarna m\u00f6jligg\u00f6r montering av skadade filsystem och ger tillg\u00e5ng till alla eller n\u00e4stan alla data i filsystemet som p\u00e5verkades av ett nyligen intr\u00e4ffat fel som ledde till skador p\u00e5 filsystemet. Felet upptr\u00e4dde n\u00e4r man efter en uppdatering av verktygen f\u00f6rs\u00f6kte, men inte slutf\u00f6rde, en uppdatering av filsystemets strukturer, varefter k\u00e4rnan med den gamla implementationen av Bcachefs f\u00f6rs\u00f6kte nedgradera versionen av strukturerna och ignorerade den of\u00e4rdiga uppdateringen. En s\u00e5dan situation ledde till att man gick in i 'split brain-l\u00e4ge', d\u00e4r ingen av operationerna kan slutf\u00f6ras och b-tree-strukturerna i filsystemet inte l\u00e4ngre \u00e4r konsistenta med det faktiska inneh\u00e5llet. <\/p>\n

Den n\u00e4mnda patchen m\u00f6jligg\u00f6r fortsatt drift \u00e4ven i s\u00e5dana fall. Bland begr\u00e4nsningarna f\u00f6r teknologin n\u00e4mns att om snapshot finns, s\u00e5 m\u00e5ste b-tr\u00e4det f\u00f6r snapshotet ocks\u00e5 vara n\u00e4rvarande och felfritt.
