I've tried to delete and reseed the passive copy and I get this error :

ErrorMessage                     : The required log file 16729 for <db>\<server> is missing on the active copy.
                                   If you removed the log file, please replace it. If the log file is lost, the databas
                                   e copy will need to be reseeded using Update-MailboxDatabaseCopy.

Help ?

it sounds like you need to get a full backup of the active/mounted database
you could also dismount it (take users offline) and run an eseutil /mh against the database, but most likely it will state this log is required

HI!

First of all you will need to Dismount the Active Copy of the Database.

Clean all the log files from the active node. You need to clear each and every log files in the directory like inspector, incseed, Eoooutofdate, etc.

Similarly clear everything on passive node where the reseed is not happening.

Than mount the database on active node, and perform the update-storagegroup for the passive copy.

let me know if you have any concerns.

Regards,
:)

jawad,

I understand the whole procedure but the first step 'clean all the log files from the active node' ?

Step 1 ) Dismount Database
Step 2 ) Delete all log files on both active and passive nodes ?  This doesn't sound right
Step 3) remount
Step 4 ) reseed

the eseutil /mh results will include a value called "Logs required"
