有哪位大哥给指点下？

yulemi 发表于 2010-10-29 09:56

rdsk下是裸设备、dsk下是块设备、md/dsk下是meta的设备

sistrong 发表于 2010-10-29 11:52

什么是META的设备，和裸设备有啥区别？

yulemi 发表于 2010-10-29 13:21

回复 4# sistrong


    met设备是你做了metainit后生成的设备，裸设备是没有建立文件系统的

cjl2029 发表于 2011-09-22 15:52

/dev/md下有dsk和rdsk但是md下还有shared、sx-app-dg这些目录下还有rdsk和dsk
这些都是什么意思啊？

财版 发表于 2011-09-22 17:39

rdsk是连接到dsk的，md是对这两个设备处理之后的设备符号。:em27:

yiguihuo 发表于 2011-09-22 18:14

用disksuite作一遍系统盘镜象保证你就明白了

财版 发表于 2011-09-22 18:44

楼上说的有理:em27:
