Vdbench测试文件系统，按照如下脚本进行测试
hd=default,vdbench=/root,user=root,shell=ssh hd=one,system=linux-test2 fsd=fsd1,anchor=/mnt/1,depth=1,width=1,files=5,size=200M,shared=yes fsd=fsd2,anchor=/mnt/2,depth=1,width=1,files=5,size=200M,shared=yes fwd=fwd1,fsd=fsd1,operation=write,xfersizes=(64K,30,512K,70),fileio=sequential,fileselect=sequential,threads=10 fwd=fwd2,fsd=fsd2,operation=read,xfersizes=(64K,30,512K,70),fileio=sequential,fileselect=sequential,threads=10 rd=rd1,fwd=(fwd1,fwd2),fwdrate=max,format=yes,elapsed=120,interval=1 |
打印如下日志后vdbench运行中止：
16:21:00.340 Message from slave one-0: 16:21:00.340 file=/mnt/2/vdb.1_1.dir/vdb_f0001.file,busy=true 16:21:00.340 file=/mnt/2/vdb.1_1.dir/vdb_f0002.file,busy=true 16:21:00.340 file=/mnt/2/vdb.1_1.dir/vdb_f0003.file,busy=true 16:21:00.340 file=/mnt/2/vdb.1_1.dir/vdb_f0004.file,busy=true 16:21:00.340 file=/mnt/2/vdb.1_1.dir/vdb_f0005.file,busy=true 16:21:00.340 Thread: FwgThread read /mnt/2 rd=rd1 For loops: None 16:21:00.340 16:21:00.340 last_ok_request: Tue Jul 17 16:20:48 EDT 2018 16:21:00.340 Duration: 11.92 seconds 16:21:00.340 consecutive_blocks: 10001 16:21:00.340 last_block: FILE_BUSY File busy 16:21:00.340 operation: read 16:21:00.340 16:21:00.340 Do you maybe have more threads running than that you have 16:21:00.340 files and therefore some threads ultimately give up after 10000 tries? 16:21:00.896 16:21:00.896 ********************************************************** 16:21:00.896 Slave one-0 aborting: Too many thread blocks 16:21:00.896 ********************************************************* |
1、检查配置文件是否编写错误，发现threads设置大于文件个数。
将threads设置改成小于或等于文件个数，如下所示（红色字体部分）：
hd=default,vdbench=/root,user=root,shell=ssh hd=one,system=linux-test2 fsd=fsd1,anchor=/mnt/1,depth=1,width=1,files=5,size=200M,shared=yes fsd=fsd2,anchor=/mnt/2,depth=1,width=1,files=5,size=200M,shared=yes fwd=fwd1,fsd=fsd1,operation=write,xfersizes=(64K,30,512K,70),fileio=sequential,fileselect=sequential, threads=5 fwd=fwd2,fsd=fsd2,operation=read,xfersizes=(64K,30,512K,70),fileio=sequential,fileselect=sequential, threads=5 rd=rd1,fwd=(fwd1,fwd2),fwdrate=max,format=yes,elapsed=120,interval=1 |
无
Vdbench，aborting，thread blocks。
