Zimbra holds BLOB message files open - how to solve?

Hi everyone,

I have an issue customizing Zimbra. I need to have each mailbox located on different mount point, mounting/unmounting them on login/logout.
For now - I face the situation when I cannot unmount user BLOB storage (/opt/zimbra/store/x/yy) because message files remain open(hold) by JAVA process even after user logout. This happens if any email message was open during user session. Please find below output of lsof command:

Code:

---

[root@aaa store]# lsof /opt/zimbra/store/0/5
COMMAND  PID  USER  FD  TYPE DEVICE SIZE/OFF NODE NAME
java    28801 zimbra  216r  REG  253,1    2720  20 /opt/zimbra/store/0/5/msg/0/340-13900.msg
java    28801 zimbra  226r  REG  253,1    1944  17 /opt/zimbra/store/0/5/msg/0/300-6600.msg

I am not so familiar with zimbra source/administration to avoid/fix this.

Can anyone help me with this?
Any help/advise is appreciated!

Thank you very much in advance!

I think you cannot do so, because Zimbra needs to access to the blob files also when users are logged out (shares items, mailbox purging etc...).

I am not sure if you can have "each mailbox located on different mount point, mounting/unmounting them on login/logout".

But the reason "message files remain open(hold) by JAVA process even after user logout" could be that mailboxd keep message cache for blobs, i guess.
