Kent Overstreet, Bcachefs failos\u00fcsteemi arendaja, pakkus v\u00e4lja plaastrid, mis v\u00f5imaldavad Linuxi k\u00e4rul t\u00f6\u00f6tada Bcachefs failos\u00fcsteemidega, isegi kui m\u00e4rkimisv\u00e4\u00e4rne osa metainfot on rikutud, taastades v\u00f5imalusel rikkis b-puid metainfost inode ja dirent struktuuride kaudu. Muudatused on vastu v\u00f5tnud Linus Torvalds ja need on lisatud t\u00e4nasesse testversiooni 6.9-rc3. <\/p>\n

Muutatused v\u00f5imaldavad kahjustatud failis\u00fcsteemide (FS) mountingut ja annavad ligip\u00e4\u00e4su k\u00f5ikidele v\u00f5i peaaegu k\u00f5igile andmetele, mis on FS-is, mida hiljutine viga on m\u00f5jutanud, h\u00e4vitades FS-i. Viga ilmus, kui p\u00e4rast t\u00f6\u00f6riistade v\u00e4rskendamist tehti, kuid ei l\u00f5petatud, katse FS-i struktuure v\u00e4rskendada, mille j\u00e4rel tuum vanas Bcachefs'i teostuses \u00fcritas struktuuride versiooni allapoole viia, eirates l\u00f5petamata v\u00e4rskendust. Selline olukord viis 'split brain mode' sisse, kus \u00fckski operatsioon ei saa l\u00f5pule viidud, ning b-tree FS-i struktuurid ei olnud enam koosk\u00f5las tegeliku sisuga. <\/p>\n

Mainitud plaastrid v\u00f5imaldavad j\u00e4tkata t\u00f6\u00f6d isegi sellistes olukordades. Tehnoloogia piirangutena mainitakse, et kui olemas on sn\u00e4pshad, peab b-snaipide puu olema olemas ja korras.
