Setting rados_mon_op_timeout/rados_osd_op_timeout with RGW

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Currently when something goes wrong with the backing Ceph cluster a RGW will block for ever because RADOS operationgs block indefinitely.

Using 'rados_osd_op_timeout' and 'rados_mon_op_timeout' we can tune this behaviour by setting timeouts to 30 seconds. [0]

By doing so we can give clients back a proper error instead of just hanging there.

I'm just wondering, is there a danger here which I don't see? Possible corruption of multipart uploads not succeeding and corrupting that way for example?

I can't think of a reason, but maybe somebody else has a clever insight on this.

Wido
