2024年10月Linux系统怎么配置多路径(2)

发布时间:

  ⑴、重启服务器后,我们可以看到多路径信息了:

  ⑵[rootRKDB ~]# ll /dev/mapper/

  ⑶crw------- root root , - : control

  ⑷brw-rw---- root disk , - : mpath

  ⑸brw-rw---- root disk , - : mpath

  ⑹[rootRKDB ~]# multipath -ll

  ⑺mpath (dbbf dm- TOYOU,Stor_iSUM

  ⑻[size=.T][features=][hwhandler=][rw]

  ⑼_ round-robin [prio=][active]

  ⑽_ ::: sdc : [active][ready]

  ⑾_ ::: sde : [active][ready]

  ⑿mpath (dbadcabda dm- TOYOU,Stor_iSUM

  ⒀[size=G][features=][hwhandler=][rw]

  ⒁_ round-robin [prio=][active]

  ⒂_ ::: sdb : [active][ready]

  ⒃_ ::: sdd : [active][ready]

  ⒄、通过fdisk 看可以生成了DM-/DM-两个盘,正是上面sdc/sde,sdb/sdd多路径后出来的:

  ⒅[rootRKDB ~]# fdisk -l

  ⒆Disk /dev/sda: . GB, bytes

  ⒇ heads, sectors/track, cylinders

  ⒈Units = cylinders of * = bytes

  ⒉Device Boot Start End Blocks Id System

  ⒊/dev/sda * + Linux

  ⒋/dev/sda Linux

  ⒌/dev/sda + Linux

  ⒍/dev/sda + Extended

  ⒎/dev/sda Linux

  ⒏/dev/sda Linux

  ⒐/dev/sda Linux swap / Solaris

  ⒑/dev/sda + Linux

  ⒒Disk /dev/sdb: . GB, bytes

  ⒓ heads, sectors/track, cylinders

  ⒔Units = cylinders of * = bytes

  ⒕Disk /dev/sdb doesn‘t contain a valid partition table

  ⒖Disk /dev/sdc: . GB, bytes

  ⒗ heads, sectors/track, cylinders

  ⒘Units = cylinders of * = bytes

  ⒙Disk /dev/sdc doesn’t contain a valid partition table

  ⒚Disk /dev/sdd: . GB, bytes

  ⒛ heads, sectors/track, cylinders

  ①Units = cylinders of * = bytes

  ②Disk /dev/sdd doesn‘t contain a valid partition table

  ③Disk /dev/sde: . GB, bytes

  ④ heads, sectors/track, cylinders

  ⑤Units = cylinders of * = bytes

  ⑥Disk /dev/sde doesn’t contain a valid partition table

  ⑦Disk /dev/dm-: . GB, bytes

  ⑧ heads, sectors/track, cylinders

  ⑨Units = cylinders of * = bytes

  ⑩Disk /dev/dm- doesn‘t contain a valid partition table

  ⅠDisk /dev/dm-: . GB, bytes

  Ⅱ heads, sectors/track, cylinders

  ⅢUnits = cylinders of * = bytes

  ⅣDisk /dev/dm- doesn’t contain a valid partition table

  ⅤDisk /dev/sdf: MB, bytes

  Ⅵ heads, sectors/track, cylinders

  ⅦUnits = cylinders of * = bytes

  ⅧDevice Boot Start End Blocks Id System

  Ⅸ/dev/sdf * + b W FAT

  ⅩPartition has different physical/logical endings:

  ㈠phys=(, , logical=(, ,

  ㈡[rootRKDB ~]#

  ㈢、我们同时也可以在/dev/mapper目录中查看到多路径映射的信息:

  ㈣[rootRKDB ~]# ll /dev/mapper/

  ㈤crw------- root root , - : control

  ㈥brw-rw---- root disk , - : data-data

  ㈦brw-rw---- root disk , - : mpath

  ㈧brw-rw---- root disk , - : mpath

  ㈨以上就是Linux系统配置多路径的教程,好像步骤比较多,但是这也是学习Linux的基础。
