Hi,
Suppose you have a hardware raid attached to a sun box.
You have RAID5 luns on that raid.
You want to use 'ufs' file systems (no Veritas, or other 'extra' software).
You build your ufs file systems.
Then on the hardware side you grow the raid (or raidset or lun or how ever
you want to call the storage unit you are talking about).
Now I want to grow the filesystem on the Sun side without rebuilding the
file system from scratch.
A double question here:
1. Is my understanding correct that the ONLY way to do using Solaris as it
comes out of the box is the following:
-use Volume mananger to create a soft partition on the lun (raidset, storage
unit, ...)
-build a normal ufs filesystem using newfs
-then when the storage unit size grows on the hardware size you do the
following:
- growfs -M /myfilesystem /dev/md/rdsk/20
Your data stays available, but it is write locked while the command is
running
2. Does anybody know if there is a perfomance penalty for using the soft
partition feature of Volume Manager?
And if so what would be that penalty?
I am looking here for people who have handson experience on this subject.
If anything usefull comes back (which I do not doubt) I will summurize.
Thanks
Bart
