I have compiled liblmdb using the mdb.master branch and used the mdb_copy as you've
suggested. It didn't produce any errors. However, when I copy the data.mdb back to the
Zimbra server it still produces the same error:
Feb 13 18:30:03 mail-archive slapd: mdb_entry_decode: attribute index 560427631 not
Then unfortunately you just have bogus attribute data in the DB. Seems unlikely that
you'll be able
to sort this out, it may actually be a disk media failure.
and when I am trying to reindex I get:
zimbra@mail-archive:~/data/ldap/mdb/db$ /opt/zimbra/libexec/zmslapindex -vv
5c64631c mdb_entry_decode: attribute index 560427631 not recognized

My broken ldap data folder contains the following files:
zimbra@mail-archive:~/data/ldap/mdb/db$ ls -la
drwxr-xr-x 1 zimbra zimbra 60 Feb 4 12:12 .

-rw-r----- 1 root root 10485759 Feb 4 12:12 log.0000000001
I can see there is the log file log.0000000001. I don't know how do I check or roll
back data using this log file? I haven't managed to find anything useful by googling.
LMDB doesn't use log files. Apparently you've let some other software overwrite
