시스템에 현재 상태로 구성이 되어 있는데
vg05에 보면 /dev/dsk/c4t13d0 의 PV Status 가 unavailable
되어 있는데 lvoldisplya 의 미러내용엔 current라 나오는데
뭐가 문제 일까요 그리고 현재 상태를 보면
/dev/dsk/c4t12d0과 /dev/dsk/c5t12d0 이 미러되있고
이서서 /dev/dsk/c4t13d0 과 /dev/dsk/c5t13d0 이 미러되있는 상태입니다.
4개가 vg05/lovl1에 묶여 있는데
문제는 이것이 미러링만 되있는건지
lvdisplay 상에서는 미러링만 되있는걸로 보이는데
단순 vgextend 인지 아니면 스트라이핑이 되있는지
되있다면 어떻게 디스크를 교체 해야 하는지 알고 싶습니다.
#strings /etc/lvmtab으로 보면 이순서대로 보입니다.

그런데 의문점은 pv status가 unavailable인데 current라는 것입니다.
