[sheepdog-users] Storage limit to 4T per node with full replica and less with erasure code

[Valerio Pachera]

Yesterday I had problem with my production cluster because i forgot to
change fd limit on a node, so it behaved like the hard disk was busy.

I had to kill -9 sheep and everything worked fine.

That made me think about the number of object we can store on a single node.
On debian I can't set a higher value than

  ulimit -Hn 1024000
  ulimit -Sn 1024000

That means 1024000*4M/1024 = 4000G (less than 4T).

If we use erasue code with a schema like 4:2, each file has 1M size so,

That means 1024000*1M/1024 = 1000G (less than 1T).

Am I correct?
