Restore HSM volumes
Problem
How to restore lost HSM volume
Solution:
1) Restore an account backup to a new account
2) Recreate the filesystem HSM path for the existing account
3) Move the restored HSM blobs to the correct filesystem path
4) Delete the restored account
Preliminary: you need to have the replacement HSM volume mounted at the same path as the old one. For example:
zmvolume -l Volume id: 1 name: message1 type: primaryMessage path: /opt/zimbra/store compressed: false current: true Volume id: 2 name: index1 type: index path: /opt/zimbra/index compressed: false current: true Volume id: 3 name: hsm1 type: secondaryMessage path: /opt/zimbra/hsm compressed: false current: true
In the above example, /opt/zimbra/hsm was the HSM store. Mount the replacement at /opt/zimbra/hsm, and make sure to
chown zimbra:zimbra /opt/zimbra/hsm
1) Restore from a full account backup to a new account:
zmrestore -rf -a account@example.com -ca -pre "hsm_"
Depending on the HSM policy (30 days default), you need to be sure the latest full backup is newer than that (?).
2) Gather account data:
- Mailbox ID:
zmprov gmi account@example.com | grep mailboxId Mailbox ID: 4
- Account Hash (substitute actual Mailbox ID):
perl -e "print (mailboxId>>12)" Account Hash: 0
- Restored Mailbox ID:
zmprov gmi hsm_account@example.com | grep mailboxId Restored MailboxID: 37
- Restored Account Hash (substitute actual Mailbox ID):
perl -e "print (mailboxId>>12)"
Restored Account Hash: 0
3) Recreate the filesystem HSM path for the existing account (/opt/zimbra/hsm/Account Hash/MailboxID):
mkdir -p /opt/zimbra/hsm/0/4
4) Move the HSM blobs from the restored account to the real account:
mv /opt/zimbra/hsm/Restored Account Hash/Restored MailboxID/msg /opt/zimbra/hsm/Account Hash/MailboxID/
Actual:
mv /opt/zimbra/hsm/0/37/msg /opt/zimbra/hsm/0/4/
5) Delete the restored account:
zmprov da hsm_account@example.com
6) Restart mailboxd for account to see HSM blobs:
zmmailboxdctl restart
7) Log in to account (account@example.com) and verify HSM messages are there
