Besides RAM, zfs requires that architecture kernel stack size is at least 12KB or more - some |
|
operations cause stack overflow with 8KB kernel stack. On NetBSD, the architectures |
|
with 16KB kernel stack are amd64, sparc64, powerpc, and experimental ia64, hppa. mac68k and sh3 have 12KB kernel |
|
stack. All others use only 8KB stack, which is not enough to run zfs. |
