Block Size During Install

[Pflynn]

Hello,

I have a situation where there is a new build ver 4.0 server - local storage is 2.6 TB - I know local storage limits for any single drive is 2 TB, so I split it into 1 TB and 1.6 TB - However, in our old 3.5 way of doing things, I'd reformat the vmfs to a more appropriate block size than 1 MB. Now , however, the service console is already put in the first vmfs. So, should the best practice be to (a) size down the first vmfs to only accomodate the sc, or (b) is there another way of modifying the block size that I am not aware of?

Thanks for any/all assistance

The best idea is alway to format the VMFS later.

Both to be able to choose the right block size and both to be sure that disk alignment is well done.

PS: if possible create 3 virtual disk. One for ESX, and 2 (with < 2TB) for VMFS.

Hello,

Thanks for your response. I do usually reformat after, but the Service console is now stored there, so I cannot. Are you aware of any alternatives?

Best regards

Right. The first datastore could be a problem

Are you aware of any alternatives?

No idea... sorry.

As far as I'm aware there's currently no option to change the blocksize during the installation or afterwards. The best option would be to create a small disk on which the VMFS will reside for the Service console and create multiple or one large(depending on the size) LUN/Disk for the other VMFS volumes.

OK thanks,

Since console is 8 GB, in terms of best practice, how much space should be allocated? IE do we need to allow for growth? I am guestimating....20 GB?

Merci,

Paul

Service Console min size requirement is around 9 GB. You can have a vmfs disk of 15 Gb and that should serve you good.

FWIW, if you forsee youself using the service console for a lot of things, you should plan your service console partitioning better i.e, accomodate extra space in /home , /tmp etc...create custom partitions as per your requirement.
