I've been asked to increase space in a FS that is currently 740G in size:
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d664 740G 424G 308G 58% /ora_back
My SAN administrator has allocated 5 LUNs of 200G each - this will make the total 1.7TB.
I know I can add the LUNs with 'metattach' but can I use 'growfs' to increase the FS size larger than 1 TB ? Are there any gotchas with growing a FS over 1TB that was not created with 1TB parameters?
I am running Solaris 10 8/07 on a v490 with kernel patch 141444-09 (latest).
Do you really need a FS that size rather than two of approx 900GB?
I see mainly possible perf issue but not knowing what this space is for, it may not be the case...
vbe - I just go by what the DBA's request. Unfortunately, they run the show in my shop.
Any way, I thought I'd post the solution I implemented last night. It goes along the lines of what one of my college professors said many times: "If you can't find a solution, you need to redefine the problem until you can."
Since I was adding a larger filesystem than I had (1TB vs. 750GB), I created a metadevice of the 5 200GB disks and created a filesystem that would grow over 1TB (newfs -T). I then copied the existing filesystem onto the newly created filesystem, cleared the old metadevice and added those slices to the new device. Now I have a filesystem that I can grow above 1TB.
