Topic: How well does gparted handle very large filesystems? >3TB

I'm now in the latter planning stages of building a new fileserver for work, part of my plan involves initially setting up the RAID array with 7x 750GB drives and then later (probably a week) adding an eighth drive and growing the partition.

The filesystem will most likely be ext3 at this time, unless someone thinks XFS or JFS is more appropriate. (Reiser isn't in the running because of this whole wife thing)

Would gparted have any problems with this?

The system would most likely at this time be Centos 4.4 with the 2.6.19 kernel. (the raid card will probably be the amcc 3ware 9650)

Internally gparted mostly works with 512 bytes sectors which are defined as 'long long'. Hence the largest number of sectors gparted can handle is 2^64 / 512 == 36028797018963968 sectors ==
16384 PiB

In short, you should be fine smile

Thanks for the info, i've now become undecided on whether to make that extra drive a hot spare instead though.  smile
