"[PATCH] md: fix is_mddev_idle calculation now that disk/sector accounting happens when request completes\n\nmd needs to monitor the rate of requests to its devices when doing\nresync/recovery so that it can back-off when there is non-resync IO. It\ndoes this by comparing resync IO, which it counts, with total IO which is\ntaken from disk_stats.\n\ndisk_stats were recently changed to account sectors when a request\ncompletes instead of when it is queued. This upsets md\u0027s calculations.\n\nWe could do the sync_io accounting at the end of requests too, but that has\nproblems. If an underlying device is an md array, the accounting will\nstill be done when the request is submitted. This could be changed for\nsome raid levels, but it cannot be changed for raid0 or linear without\nsubstantial code changes.\n\nSo instead, we increase the error that is_mddev_idle allows, up to the\nmaximum amount of resync IO that can be in flight at any time. The\ncalculation is current fragile as each personality as different limits for\nin-flight resync. This should be fixed up.\n\nFor now, this simple patch fixes the problem.\n\nIncreasing the error margin decreases the sensitivity to non-resync IO. To\npartially compensate for this, the time to wait when non-resync IO is\ndetected is increased so that less steady IO is required to keep the resync\nat bay.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "93588e2284b6be1873cc0bb7fbf0947bdbf72830", "tree": "685a5b21312c6d057f1db37d75085944db646cb9", "parents": [ "e8a0033451f7972169b2f375be34d9d805ad8687" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Tue Nov 15 00:09:12 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Nov 15 08:59:19 2005 -0800" }, "message": "[PATCH] md: make md threads interruptible again\n\nDespite the fact that md threads don\u0027t need to be signalled, and won\u0027t\nrespond to signals anyway, we need to have an \u0027interruptible\u0027 wait, else\nthey stay in \u0027D\u0027 state and add to the load average.\n\n(akpm: the signal_pending() test is unneeded - we\u0027ll fix that up in the next\nround.
