[OpenAFS] questions about volume size?

[Sam Tseng]

sorry to bother you guys. i think i found the answer. :$

i tried to move this home.rwaur volume before. so, it did clone before move it.

when i list volume in partition c only has one volume home.rwaur. but,
i list /vicepc/. it shows three volumes. so i zap them. however, i
don't know is this correct way to do this or not? but, it works.

[root@fs +]# vos listvol fs
Total number of volumes on server fs partition /vicepc: 1
home.rwaur                        536871041 RW 1036276240 K On-line

Total volumes onLine 1 ; Total volumes offLine 0 ; Total busy 0

[root@fs vicepc]# ls
AFSIDat  Lock  lost+found  V0536871041.vol  V0536871168.vol  V0536871171.vol
[root@fs vicepc]# vos zap -server fs -id 0536871168
vos: Missing required parameter '-partition'

[root@fs vicepc]# vos zap -server fs -partition c -id 536871168
Volume 536871168 deleted

[root@fs vicepc]#vos zap -server fs -partition c -id 536871171
Volume 536871171 deleted

thank you all!!

best, s
