    Default Zimbra consistency checks?

    The drive I had the bulk of my Zimbra VM on has just decided it wants to develop some bad sectors. Funfunfun.

    As quite a bit has happened since I last took a backup this morning [an upgrade and some important mail coming in] I'm trying to rescue the current system rather than rolling back to the last backup. Currently dd_rescude reports only 8Kb of bad reads so far [~30Gb of 60Gb partition copied so far], so if I'm very luck and those couple of blocks do not contain a critical bit of file-system structure I might get away with it.

    After starting the VM in single user mode to run fsck on all the affected volumes, are there any useful commands I can run or other things to look at to double-check there are no serious detectable errors in the LDAP records the database, or other parts of Zimbra, before I let it try to start up properly?

    I'll probably do a reinstall, restore from backup, and migrate missing data via imapsync later - but for now hopefully this will be "safe enough" and get access to stuff that cam in this afternoon...

    Why do these things always happen on a gloriously pleasant summer day when I'd rather be anywhere but in front of a broken machine?!

    Sorry you've had trouble!!

    I would suggest that you try to start up the critical components independently before running them all.

    So, open 2 terminal windows, 1 for running the process, the other for tailing the log for info.

    format:
    command - log
    ldap start - /var/log/zimbra.log
    mysql.server start - /opt/zimbra/db/data/(hostname).err

    Once those get started up without error, then keep the two above running, then run
    zmmailboxdtl start - /opt/zimbra/log/zmmailboxd.out

    Good luck!
