有一台主機redhat 5.x已有一組raid-1的disk,用LVM管理(前人做的) 後來新增2個disk,做成第2個raid-1,在linux看到是/dev/sdb 已經切成/dev/sdb1,並format了 以下是fdisk -l的訊息 Disk /dev/sdb: 999.9 GB, 999999668224 bytes 255 heads, 63 sectors/track, 121576 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 121576 976559188+ 83 Linux Disk /dev/dm-2: 999.9 GB, 999999668224 bytes 255 heads, 63 sectors/track, 121576 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/dm-2p1 1 121576 976559188+ 83 Linux Disk /dev/dm-3: 999.9 GB, 999996609024 bytes 255 heads, 63 sectors/track, 121575 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-3 doesn't contain a valid partition table https://imgur.com/3nt17Se.jpg
但要mount時,就是有這訊息 # mount /dev/sdb1 /u03 mount: /dev/sdb1 already mounted or /u03 busy # dmsetup ls mpath5p1 (253, 3) VolGroup00-LogVol01 (253, 1) mpath5 (253, 2) VolGroup00-LogVol00 (253, 0) https://imgur.com/8XwDy4N.jpg
/dev/dm-2跟/dev/dm-3 都是系統自己生出來的 用LVM GUI介面對/dev/sdb做initilize 也不行,說已在使用 (我linux的LVM不是很熟) google一些文件後,是否要把multipath移除 ? 1.才能直接mount /dev/sdb1 2.或是加到LVM管理 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 118.166.230.9 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Linux/M.1635088408.A.8EA.html

如果要移除的話,是否移除mpath5,還是要先移除 mpath5p1 ? multipath -f mpath5 不會影響原本的這2個lv吧? VolGroup00-LogVol01 VolGroup00-LogVol00 ※ 編輯: chings22 (118.166.230.9 臺灣), 10/25/2021 18:14:54
