Jeff Bonwick has suggested a fix to 6528296 (system hang while zvol swap space shorted). If we can get that fixed, then it may become safe to use true zvols for swap. I'll update the bug with his suggested fix (and probably ping him on it too, to see if he wants to elaborate). Even if the bug is fixed however, we might want this new kind of zvol for performance reasons. But you're right. We shouldn't leave things as they are. We should either fix the bug, or stop telling people that it's OK to use zvols for swap. > Would we have the same > sort of issue with the dump device so we need to fix it anyway? > The current implementation of zvols, even if the above-mentioned bug were fixed, will not support dump. It would be too complicated to write to them in the panic path. That was the other reason for implementing pseudo-zvols (or zslices, or whatever).
