355.Fx 8.0 . 356.Sh BUGS 357The handling of spare drives appears to be unreliable. 358The 359.Xr mpt 4 360firmware manages spares via spare drive 361.Dq pools . 362There are eight pools numbered 0 through 7. 363Each spare drive can only be assigned to a single pool. 364Each volume can be backed by any combination of zero or more spare pools. 365The 366.Nm 367utility attempts to use the following algorithm for managing spares. 368Global spares are always assigned to pool 0, 369and all volumes are always backed by pool 0. 370For dedicated spares, 371.Nm 372assigns one of the remaining 7 pools to each volume and 373assigns dedicated drives to that pool. 374In practice however, it seems that assigning a drive as a spare does not 375take effect until the box has been rebooted. 376Also, the firmware renumbers the spare pool assignments after a reboot 377which undoes the effects of the algorithm above. 378Simple cases such as assigning global spares seem to work ok 379.Pq albeit requiring a reboot to take effect 380but more 381.Dq exotic 382configurations may not work reliably. 383.Pp 384Drive configuration commands result in an excessive flood of messages on the 385console. 386.Pp 387The mpt version 1 API that is used by 388.Nm 389and 390.Xr mpt 4 391does not support volumes above two terabytes. 392This is a limitation of the API. 393If you are using this adapter with volumes larger than two terabytes, use the adapter in JBOD mode. 394Utilize 395.Xr geom 8 , 396.Xr zfs 8 , 397or another software volume manager to work around this limitation.
