We have a sysadmin configure a couple of servers at digitalocean. To me, it looks like swap wasn't enabled on this but it's been a VERY long time since I've had to do things like this. It's a rails app and the only reason this came up is because we were getting out of memory errors. Is a swap partition still considered a best practice for a modern (3.2.13 rails app)? I'd imagine so. Is there a simple fix to creating a swap partition from the command line (host has 2GB of RAM)? Not asking to do it but some guidance would be appreciated.
I'm fine with just upgrading to a 1GB of memory server which is only $5 / month more.
deploy@x1:~$ sudo fdisk -l Disk /dev/sda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders, total 83886080 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sda doesn't contain a valid partition table deploy@x1:~$
Alos should I be concerned about the last line regarding not containing a valid partition table?
Disk /dev/sda doesn't contain a valid partition table
I saw this mentioned y-day too and the answer was no. – Rinzwind Apr 10 '13 at 18:52free -m

sort of depends on what is using your memory as suggested by TLOT "doesn't contain a valid partition table" does not seem to be a problem, my guess is you are using LVM or encryption, post the output ofmount
