SUN的DISKSUITE

SUN的DISKSUITE看来真是不太可靠.
今天一个数据库出了问题，07445导致数据库crash掉了.
别的问题没发现，但是发现DiskSuite的镜像盘出了问题.
使用metastat检查:
root:/usr/opt/SUNWmd/sbin>df -k
Filesystem kbytes used avail capacity Mounted on
/proc 0 0 0 0% /proc
/dev/md/dsk/d10 2056211 496291 1498234 25% /

metareplace d10 c0t11d0s0

发现磁盘镜像的状态是Needs maintenance，需要进一步研究诊断。
历史上的今天...
