Hi everyone,
I am currently about to upgrade from 4.0B to 4.0D on a Alpha 2100, but
first I’m going to have to increase the size of the root domain (Currently
64M with only about 5M free )
I’m new to the Digital disk layouts, so I just want to check what is the
best method to upgrade the root domain. The current layout is as such,
with root, usr , and swap being on the one disk (4.2Gb).......
8 partitions:
# size offset fstype [fsize bsize cpg]
a: 131072 0 AdvFS # (Cyl. 0 - 31)
b: 262144 131072 swap # (Cyl. 32 - 95)
c: 8378368 0 unused 1024 8192 # (Cyl. 0 - 2045*)
d: 0 0 unused 1024 8192 # (Cyl. 0 - -1)
e: 0 0 unused 1024 8192 # (Cyl. 0 - -1)
f: 0 0 unused 1024 8192 # (Cyl. 0 - -1)
g: 7985152 393216 AdvFS # (Cyl. 96 - 2045*)
h: 0 0 unused 1024 8192 # (Cyl. 0 - -1)
The system is a high availability one. As a safe guard, I’ve got a spare
disk. I plan on copying the usr, swap, and increased root to the new
disk, and then making this spare disk part of the system. This way, if
anything terrible happens, I’ll still have the old (untouched) root disk
to simply slot back in, and re-start the system (Well, that’s the theory
anyway). The existing and spare disk are both single 4.2Gb drives.
I’m just after any suggestions as to the best way to to this. I’m still
learning up on AdvFS, so I’m not sure about the best way to copy the
domains. Should I copy to tape as well, or is this overkill???
Current H/W: DEC2100_C500
Current O/S: UNIX V4.0B (Rev. 564)
PS – Any suggestions for the size of root on 4.0D? The upgrade manuals
have gone “missing” so I can’t find any immediate information on suggested
sizing.
Thanks for your help,
Reg,
Dirk.
