[Ocfs2-devel] Could someone tell me the function of LVB, thanks
Hi all, In my 10 nodes cluster, I find some strange logs in kernel.log when operating some days. logs as follws: May 14 14:01:33 cvk68 kernel: [272684.537063] (umount,52420,10):dlm_prepare_lvb_for_migration:1216 ERROR: Mismatched lvb in lock cookie=8:982, name=M00000000000000007e012000000000, node=8 May 14 14:01:33 cvk68 kernel: [272684.537066] lockres: M00000000000000007e012000000000, owner=6, state=32 May 14 14:01:33 cvk68 kernel: [272684.537067] last used: 0, refcnt: 11, on purge list: no May 14 14:01:33 cvk68 kernel: [272684.537068] on dirty list: no, on reco list: no, migrating pending: no May 14 14:01:33 cvk68 kernel: [272684.537069] inflight locks: 0, asts reserved: 0 May 14 14:01:33 cvk68 kernel: [272684.537069] refmap nodes: [ 1 2 3 4 5 7 8 9 10 ], inflight=0 May 14 14:01:33 cvk68 kernel: [272684.537073] granted queue: May 14 14:01:33 cvk68 kernel: [272684.537074] type=3, conv=-1, node=2, cookie=2:949, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537075] 050000000000005900000000000000001554ffffffc162ffffffec2a26ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd40000000005ffffffa00000ffffff81ffffff800001000000006d16ffffffc96400000000 May 14 14:01:33 cvk68 kernel: [272684.537092] type=3, conv=-1, node=5, cookie=5:1103, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537094] type=3, conv=-1, node=4, cookie=4:1117, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537095] type=3, conv=-1, node=1, cookie=1:987, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537096] type=3, conv=-1, node=7, cookie=7:973, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537097] 050000000000005900000000000000001554ffffffc162ffffffec2a26ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd40000000005ffffffa00000ffffff81ffffff800001000000006d16ffffffc96400000000 May 14 14:01:33 cvk68 kernel: [272684.537114] type=3, conv=-1, node=8, cookie=8:982, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537116] type=3, conv=-1, node=10, cookie=10:632, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537117] 050000000000005900000000000000001554ffffffc162ffffffec2a26ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd40000000005ffffffa00000ffffff81ffffff800001000000006d16ffffffc96400000000 May 14 14:01:33 cvk68 kernel: [272684.537135] type=3, conv=-1, node=3, cookie=3:988, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537136] type=3, conv=-1, node=9, cookie=9:399, ref=2, ast=(empty=y,pend=n), bast=(empty=y,pend=n), pending=(conv=n,lock=n,cancel=n,unlock=n) May 14 14:01:33 cvk68 kernel: [272684.537137] 050000000000005900000000000000001554ffffffc162ffffffec2a26ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd41554ffffffc162ffffffeaffffffbbfffffff0ffffffd40000000005ffffffa00000ffffff81ffffff800001000000006d16ffffffc96400000000 May 14 14:01:33 cvk68 kernel: [272684.537154] converting queue: May 14 14:01:33 cvk68 kernel: [272684.537154] blocked queue: This seems nodes [ 2 7 9 10 ] have lvb value, but nodes [ 1 3 4 5 8 ] don't have. So, my question is: 1, What is the function of LVB ? 2, In which case this issue occurs? 3, If the value of LVB is meaningless, could we do not compare them between different nodes?
