[Gluster-users] [Error] 0-iobuf: invalid argument: iobuf (or iobref)
Hi: I'v been experiencing an intermittent issue with GlusterFS in 30 nodes cluster which makes the mounted file system unavailable through the GlusterFS client. The symptom is: $ ls /gluster ls: cannot access /gluster: Transport endpoint is not connected the client log reports the following error: [2016-08-09 23:25:36.012877] E [iobuf.c:759:iobuf_unref] (--> /usr/lib64/libglusterfs.so.0(_gf_log_callingfn+0x1e0)[0x371a220580] (--> /usr/li b64/glusterfs/3.6.7/xlator/performance/quick-read.so(qr_readv_cached+0xb7)[0x7ff57f318ea7] (--> /usr/lib64/glusterfs/3.6.7/xlator/performance/ quick-read.so(qr_readv+0x62)[0x7ff57f3194c2] (--> /usr/lib64/libglusterfs.so.0(default_readv_resume+0x14d)[0x371a22a75d] (--> /usr/lib64/libgl usterfs.so.0(call_resume+0x3d6)[0x371a2424b6] ))))) 0-iobuf: invalid argument: iobuf [2016-08-09 23:25:36.013192] E [iobuf.c:865:iobref_unref] (--> /usr/lib64/libglusterfs.so.0(_gf_log_callingfn+0x1e0)[0x371a220580] (--> /usr/l ib64/glusterfs/3.6.7/xlator/performance/quick-read.so(qr_readv_cached+0xc1)[0x7ff57f318eb1] (--> /usr/lib64/glusterfs/3.6.7/xlator/performance /quick-read.so(qr_readv+0x62)[0x7ff57f3194c2] (--> /usr/lib64/libglusterfs.so.0(default_readv_resume+0x14d)[0x371a22a75d] (--> /usr/lib64/libg lusterfs.so.0(call_resume+0x3d6)[0x371a2424b6] ))))) 0-iobuf: invalid argument: iobref seems to me it's the out-of-memory issue. info: glusterfs is configured as follows performance.io-thread-count: 4 performance.cache-max-file-size: 0 performance.write-behind-window-size: 64MB performance.cache-size: 4GB cluster.consistent-metadata: on and each node in cluster are deployed both glusterfs client and server. is there any way to ease the above issue via modify configuration? such as increase cache-size, or some other paramters? thx. -------------- next part -------------- An HTML attachment was scrubbed...
