The functions cp and kjournald were blocked in did vary, but\nkmirrord\u0027s wchan always pointed to \u0027mempool_alloc()\u0027. We\u0027ve seen this pattern\non 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates\nthat this problem has been around even before.\n\nSo much for the facts, here\u0027s my interpretation: mempool_alloc() first tries\nto atomically allocate the requested memory, or falls back to hand out\npreallocated chunks from the mempool. If both fail, it puts the calling\nprocess (kmirrord in this case) on a private waitqueue until somebody refills\nthe pool. Where the only \u0027somebody\u0027 is kmirrord itself, so we have a\ndeadlock.\n\nI worked around this problem by falling back to a (blocking) kmalloc when\nbefore kmirrord would have ended up on the waitqueue. This defeats part of\nthe benefits of using the mempool, but at least keeps the system running. And\nit could be done with a two-line change. Note that mempool_alloc() clears the\nGFP_NOIO flag internally, and only uses it to decide whether to wait or return\nan error if immediate allocation fails, so the attached patch doesn\u0027t change\nbehaviour in the non-deadlocking case. Path is against current git\n(2.6.18-rc4), but should apply to earlier versions as well.

Since the recovery process refers to the sync_bits to find a\nregion to be recovered, the region whose state was changed from RH_NOSYNC\nto RH_CLEAN is no longer recovered.\n\nIf you haven\u0027t applied dm-raid1-read-balancing.patch proposed in dm-devel\nsometimes ago, the contents of the mirrored disk just corrupt silently. If\nyou have, balanced read may get bogus data from out-of-sync disks.\n\nThe RH_NOSYNC region will be changed to RH_RECOVERING when recovery starts\non the region and get reclaimed when the recovery completes. So it doesn\u0027t\nleak the region hash entry.\n\nAlasdair said:\n\n I\u0027ve analysed the relevant part of the state machine and I believe that\n the patch is correct.\n\n (Further work on this code is still needed - this patch has the\n side-effect of holding onto memory unnecessarily for long periods of time\n under certain workloads - but better that than corrupting data.)\n\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nAcked-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0eaae62abaa1ad1f231932b6cdd9fb1b91df6651", "tree": "cda02cffff075a8b542ddcea4fa0ff0064130502", "parents": [ "53184082b070dfb077218828fdf839826102ed96" ], "author": { "name": "Matthew Dobson", "email": "colpatch@us.ibm.com", "time": "Sun Mar 26 01:37:47 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Mar 26 08:56:59 2006 -0800" }, "message": "[PATCH] mempool: use common mempool kmalloc allocator\n\nThis patch changes several mempool users, all of which are basically just\nwrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather\nthan their own wrapper function, removing a bunch of duplicated code.\n\nSigned-off-by: Matthew Dobson \u003ccolpatch@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a1a190807074bd6ad8771e00b00752771ae586cb", "tree": "ea9df244d215722e422f7bd7560dd9fe59789f44", "parents": [ "2d5fe68987341a59a3fd97c71695efcabb0c6fd5" ], "author": { "name": "Jonathan E Brassow", "email": "jbrassow@redhat.com", "time": "Fri Jan 06 00:20:05 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:34:00 2006 -0800" }, "message": "[PATCH] device-mapper raid1: add default mirror\n\nThis patch introduces a new field to the mirror_set (default_mirror) to store\nthe default mirror.\n\n(A subsequent patch will allow us to change the default mirror in the event of\na failure.)\n\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "7692c5dd48026d952199c2b97c3418f927cc0407", "tree": "f198721b3b65a782ae0ed7400120cc45e0ce87c1", "parents": [ "233886dd32ad71daf9c21bf3728c0933a94870f0" ], "author": { "name": "Jonathan E Brassow", "email": "jbrassow@redhat.com", "time": "Mon Nov 21 21:32:37 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Nov 22 09:14:31 2005 -0800" }, "message": "[PATCH] device-mapper raid1: drop mark_region spinlock fix\n\nThe spinlock region_lock is held while calling mark_region which can sleep.\nDrop the spinlock before calling that function.\n\nA region\u0027s state and inclusion in the clean list are altered by rh_inc and\nrh_dec.
