Subject: [PATCH] Add a configurable delay to Nova Evacuate calls
|
|
|
391384 |
|
|
|
391384 |
In case /var/lib/nova/instances resides on NFS we have seen migrations
|
|
|
391384 |
failing with 'Failed to get "write" lock - Is another process using the
|
|
|
391384 |
image' errors.
|
|
|
391384 |
|
|
|
391384 |
This has been tracked down to grace/lease timeouts not having expired
|
|
|
391384 |
before attempting the migration/evacuate, so in this cases it might be
|
|
|
391384 |
desirable to delay the nova evacuate call to give the storage time to
|
|
|
391384 |
release the locks.
