7133-D40, i have make an raid5 arrary hdisk3 which is composed of 3 pdisks
and not allocate any hotspares to the raid5.
Then i make a VG on hdisk3 and create a filesystem /7133fs on the VG.
Later i do an experiment like following :
I unplug the one of the 3 pdisks and soon the raid5 array became to exposed
state.
What i felt strange was after i list the content of any file in the /7133fs
using "cat filename"
, I can found that the raid5 array became to "degraded state". Why ?
I only know that if the raid5 array was in "exposed" state and i write
something to the /7133fs then the array can switch to "degraded state", but
not reading the files can cause the "degraded state".
Any one have the same experiences ?
Thank in advance .
