Hi, This is a bugfix only release in of the 8.3 code branch. The most subtlety bug fixed with this release is in the area of the max_bio_size negotiation: Over the course of the last releases we where driving up the max_bio_size supported by DRBD. We had an optimistic negotiation of the agreed max_bio_size in place. Now, if one created a device, made it primary, connected it to a peer node with data, and attached the local disk after all that, he could cause DRBD to shrink the max_bio_size with that attach operation. But shrinking the max_bio_size is a problem if a BIO gets created with the old (larger) max_bio_size and gets submitted when the new (smaller) max_bio_size is set. The other fixes are quite on the same page: Rather not so common cases. Interesting for long distance replication users, is the bugfix for establishing connections. Please note: This is a release candidate, not intended for production. Please help with testing! 8.3.11rc1 (api:88/proto:86-96) -------- * Fixed handling of read errors during online verify runs * Fixes for possible distributed deadlocks during online verify and checksum based resync processes * Fixed handling of IO errors with an on-io-error=pass-on policy; the disk state goes to inconsistent * Fixed the behaviour in case ping-timeout and ping-int are set to the same value * Fix for connecting on high latency network links * Fixed state transitions if fence-peer handler returns after connection was established again * Made the max_bio_size negotiation conservative instead of optimistic * Network timeouts for mirrored write requests are now always enforced, no longer only when the socket is congested http://oss.linbit.com/drbd/8.3/drbd-8.3.11rc1.tar.gz http://git.drbd.org/?p=drbd-8.3.git;a=commit;h=drbd-8.3.11rc1 Best, Phil -- : Dipl-Ing Philipp Reisner : LINBIT | Your Way to High Availability : Tel: +43-1-8178292-50, Fax: +43-1-8178292-82 : http://www.linbit.com DRBD(R) and LINBIT(R) are registered trademarks of LINBIT, Austria.
