Hi,
I would like to see advice/comments on the best and safest way to expand a file system which is nearing 100% utlisation.
I've a NTFS file system on SAN( using SAN RAID 5) of about 200 GB. I've some spare disks on SAN which are unused and would like to increase the filesystem space from 200 GB to 300/400 GB. I would like to do this with minimum effort, if possible, and without deleting the existing data. I've heard about microsoft technology of using the " mount point" but is concerned on performance and how it works with hardware RAID technologies. Unfortunately I cannot increase the filesystem on SAN by adding disks as we are using old SAN technology.
MY limitations are
- budget ( may be hard to get new harddisks/server)
- Current SAN filesystem cannot increase automatically unless we create a filesystem with a new size and copy all the data from old to new or delete old filesystem, re-create a new filesystem and restore data from tape.
My options( which I'm thinking are)
- Basic to Dynamic disk and then expand filesystem (I believe I cannot do this due to complex SAN configurations changes)
- Mount point on an existing empty directory/folder ( this may not help if I need space for other folders/directory which may be above the mount point)
- Build New Server ( and transfer data from old to new)
- Any others ?
Suggestions/Inputs are welcome.
