Dear Aki,
I switched to "gz" now, since "zstd" also gave some errors
on writing to
files.
I dont know if "xz" compression or "zstd" shreddered my
MDBOX Files, but
I lost 4 days of mail. (a couple of thousand mails).
After restoring the backup (what was made after switching to version
2.3.11.3) I still have some broken mdfiles, but not too many.
Interestingly always in the "Sent" Mailbox on a number of Users.
I just can not go back to 20.08.2020 before I updated to 2.3.11.3 - too
many emails would have been lost.
So - the current status is 2.3.11.3, with "gz" compression.
I force-synced and re-indexed all the mdbox files (250 GB), but still
have some broken - please how can I fix those ?
You stated :
(In theory you could leave the existing mails xz-compressed, but best
would be to re-compress everything via dsync so old mails can be read
when we eventually remove xz support.)
what is the optimal way to do that, expecially not loosing the index (?)
for outlook/thunderbird, for third party tools that rely on some
index/hash (dunno how exactly that works) ?
