  Can't remove open logical volume "LogVol01"
===================================================================================
[root@localhost ~]# mkfs -t ext3  /dev/VolGroup00/LogVol01
mke2fs 1.39 (29-May-2006)
/dev/VolGroup00/LogVol01 is mounted; will not make a filesystem here!
##到底是誰mount了他呢？
=======================================================================
[root@localhost ~]# umount /dev/VolGroup00/LogVol01
umount: /dev/VolGroup00/LogVol01: not mounted
又說沒mount.....XD..
========================================================================

抱歉貼了一堆，我要問的是LogVol01到底在哪？我想要把他合併到LogVol00，要怎麼做呢？
謝謝
^_^

推 Adama:Vol01是swap? 看看/etc/fstab吧
→ hukhuk:感謝，就是swap...真高手~~
→ hukhuk:想問是為什麼打fdisk和mount都沒有顯示呢？
推 Adama:它在lvm裡所以fdisk不會顯示。mount的部分我也不知道 XD
→ Adama:一個可能是因為swap沒有掛載點？
→ hukhuk:感謝您...
→ dou0228:未看先猜 RH 系列
→ hukhuk:樓上，您真內行，就是Centos
→ dou0228:合併? 先用 RescueCD 開機 tar 起來再 untar 回去吧
→ hukhuk:謝謝
推 nknudragon:合併? 納妳還要不要有swap ?
→ nknudragon:1. swapon 先把swap先放掉. 2. lvreduce or lvremove
→ nknudragon:LogVol01的space釋放，放LiveCD把Logvol00 extend
→ nknudragon:因為你一進系統LV就無法umount，所以要用LiveCD去做
→ nknudragon:另解是增加一顆實體硬體硬碟，規畫成PV，納入VG裡面
→ nknudragon:然後LogVOl00這個LV就可以增加容量了
→ hukhuk:謝謝各位熱心回答，之前是不知其型態才想要合併，但現在知
→ hukhuk:道是swap，就不用再合併了…^_^
