[DRBD-user] DRBD on ZVOL

[Michael Hierweck]

Hi everybody,

would anyone tell me which settings regarding disk flushes (barriers,
flushes, drain) are recommended when using ZVOL as backing device for
DRBD? Are there recommendation towards ZFS settings such as disabling
primary or secondary caches?

Of course, reliability is more important than speed.

Thanks in advance,

Michael
