Hi David et al, We are still havin with cachefiles - even after the last few patches deployed since the 2.6.30 release. We have 3 servers - 1 x Primary DB/NFS Fileserver 2 x Clustered web boxes wit NFS caching. We are still getting cachefilesd failing occasionally on both of the web boxes. I have tried multiple varants of 2.6.30.x and .31 Here is the output from syslog - Aug 20 00:57:01 dnetwww2 cachefilesd[7046]: Refilling cull table Aug 20 00:57:01 dnetwww2 cachefilesd[7046]: Scan complete Aug 20 00:57:19 dnetwww2 Pid: 182, comm: kslowd Not tainted 2.6.31-rc6-git5 #1 Aug 20 00:57:19 dnetwww2 Call Trace: Aug 20 00:57:19 dnetwww2 [<ffffffff811434e9>] 0xffffffff811434e9 Aug 20 00:57:19 dnetwww2 [<ffffffff812b5d01>] ? 0xffffffff812b5d01 Aug 20 00:57:19 dnetwww2 [<ffffffff81032f86>] 0xffffffff81032f86 Aug 20 00:57:19 dnetwww2 [<ffffffff810331ff>] 0xffffffff810331ff Aug 20 00:57:19 dnetwww2 [<ffffffff8104f295>] 0xffffffff8104f295 Aug 20 00:57:19 dnetwww2 [<ffffffff81079aea>] 0xffffffff81079aea Aug 20 00:57:19 dnetwww2 [<ffffffff8110360d>] 0xffffffff8110360d Aug 20 00:57:19 dnetwww2 [<ffffffff8108c8c1>] ? 0xffffffff8108c8c1 Aug 20 00:57:19 dnetwww2 [<ffffffff8103320a>] ? 0xffffffff8103320a Aug 20 00:57:19 dnetwww2 [<ffffffff8108ca67>] 0xffffffff8108ca67 Aug 20 00:57:19 dnetwww2 [<ffffffff810b4478>] 0xffffffff810b4478 Aug 20 00:57:19 dnetwww2 [<ffffffff811015b6>] 0xffffffff811015b6 Aug 20 00:57:19 dnetwww2 [<ffffffff810b46f0>] 0xffffffff810b46f0 Aug 20 00:57:19 dnetwww2 [<ffffffff8113f283>] 0xffffffff8113f283 Aug 20 00:57:19 dnetwww2 [<ffffffff81141768>] ? 0xffffffff81141768 Aug 20 00:57:19 dnetwww2 [<ffffffff8113fb8d>] 0xffffffff8113fb8d Aug 20 00:57:19 dnetwww2 [<ffffffff810f95d3>] 0xffffffff810f95d3 Aug 20 00:57:19 dnetwww2 [<ffffffff81028af4>] ? 0xffffffff81028af4 Aug 20 00:57:19 dnetwww2 [<ffffffff810f9f04>] 0xffffffff810f9f04 Aug 20 00:57:19 dnetwww2 [<ffffffff81078bdc>] 0xffffffff81078bdc Aug 20 00:57:19 dnetwww2 [<ffffffff81039590>] ? 0xffffffff81039590 Aug 20 00:57:19 dnetwww2 [<ffffffff81032f86>] ? 0xffffffff81032f86 Aug 20 00:57:19 dnetwww2 [<ffffffff8104f2ba>] ? 0xffffffff8104f2ba Aug 20 00:57:19 dnetwww2 [<ffffffff81078961>] ? 0xffffffff81078961 Aug 20 00:57:19 dnetwww2 [<ffffffff8104ef7a>] 0xffffffff8104ef7a Aug 20 00:57:19 dnetwww2 [<ffffffff81011b8a>] 0xffffffff81011b8a Aug 20 00:57:19 dnetwww2 [<ffffffff8104eeeb>] ? 0xffffffff8104eeeb Aug 20 00:57:19 dnetwww2 [<ffffffff81011b80>] ? 0xffffffff81011b80 Aug 20 00:57:19 dnetwww2 CacheFiles: I/O Error: Readpage failed on backing file 4000000000000810 Aug 20 00:57:19 dnetwww2 FS-Cache: Cache cachefiles stopped due to I/O error Aug 20 00:57:31 dnetwww2 CacheFiles: File cache on sdb1 unregistering Aug 20 00:57:31 dnetwww2 FS-Cache: Withdrawing cache "mycache" Aug 20 00:57:31 dnetwww2 cachefilesd[7046]: Refilling cull table Aug 20 00:57:31 dnetwww2 cachefilesd[7046]: Failed to check object's in-use state: errno 5 (Input/output error) FYI these are Virtual Machines running under ESX4i on Dell Poweredge R200's Any feedback would be greatly appreciated. -- Linux-cachefs mailing list Linux-cachefs@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cachefs
