Bulk write replay & grant interaction

Bug Major Resolved Not a Bug Johann Lombardi Mikhail Pershin zfs Thu, 25 Oct 2012 11:38:31 +0000 Sun, 22 Jul 2018 08:19:27 +0000 Sun, 22 Jul 2018 08:19:27 +0000 Lustre 2.4.0 0 3 <p>Johann, can you please provide some details about what this bug is for? It is a clone from ORI-384, so possibly it relates to interop with old clients related to "OBD_BRW_FROM_GRANT in the rnb_flags"?</p> <p>No, it is not an interop issue and not something new in 2.4 (it has been around since bulk write replay is enabled).<br/> The issue is that we return an array of rc when processing bulk write and this array isn't resent to the server on replay. As a result, we might end up with a different result when replaying bulk writes than the original one.<br/> e.g.: page 1 was written successfully while page 2 failed with ENOSPC might end up being the two pages are successfully written during replay. </p> Related Development Project Rank 1|hzvatr: Rank (Obsolete) 5289 Severity Story Points 1.0
