asm disk on NFS/NAS in linux

743664Dec 24 2010 — edited Dec 25 2010

Hi,

Currently i am having one diskgroup of 1.5TB on SAN in linux. Now there is a requirement to increase the space in the server and the space can only be added from NFS/NAS drive. I am planning to create asm disks using 'dd' command.

I have below queries:
1. Is it feasbile to keep the asm disk from both SAN & NAS drives.
2. asm_diskstring parameter is not set as we are using multipath and created raw devices then how to set the parameter to detect the asmdisks.
3. Can any one suggest me the size of one disk on NAS in linux.
4. I tried with losetup and with this i can create upto 8 disks. If i create disk of 250GB using 'dd' command then is there any risk?

Please advice.

Thanks,
