At the time of writing GnuPG unfortunately defaults to a 1024 bit DSAkey as the primary with SHA1 as the preferred hash. Due to weaknessesfound with the SHA1 hashing algorithm Debian prefers to use keys thatare at least 2048 bits and preferring SHA2. The following instructionsprovide a guide to how to generate such a key and are based, withpermission, on a post to Ana’sblog. pub 4096R/6AA15948 2009-05-10 Key fingerprint = 7A33 ECAA 188B 96F2 7C91 7288 B346 4F89 6AA1 5948 uid Ana Beatriz Guerrero López <ana@ekaia....

Let’s assume that you don’t have a physical device failure (which is a different set of tools – mount -odegraded, btrfs dev del missing). First thing to do is to take a btrfs-image -c9 -t4 of the filesystem, and keep a copy of the output to show josef. :) Then start with -orecovery and -oro,recovery for pretty much anything. If those fail, then look in dmesg for errors relating to the log tree – if that’s corrupt and can’t be read (or causes a crash), use btrfs-zero-log....
