Linux swap 128MB limit

Is it true that latest versions of Linux still have this 128MB limit of swap? So if I need 256MB swap... do I need to break it on 2x128MB swap partitions?

Code: Select all

$ free
             total       used       free     shared    buffers     cached
Mem:       1541752     495892    1045860          0      16508     247628
-/+ buffers/cache:     231756    1309996
Swap:      2409708          0    2409708

obviously not.

No no... I googled for it... There is said that you can create larger than 128MB swap partition... but Linux will use only 128MB

The limit only applies to old swap format.

It is 128Gb on alpha, 1Gb on sparc, and 3Tb on sparc64. An opteron on the 2.6 kernel can write to a 16 Tb swap partition. For linux kernels 2.1 and earlier, the limit is 128Mb.
