I believe I ran into one or both of these bugs: 6429996 zvols don't reserve enough space for requisite meta data 6430003 record size needs to affect zvol reservation size on RAID-Z Basically what happened was that the zpool filled to 100% and broke UFS with 'no space left on device' errors. This was quite strange to sort out since the UFS zvol had 30GB of free space. I never got any replies to my request for more info and/or workarounds for the above bugs. My workaround and recommendation is to leave a 'healthy' amount of un-allocated space in the zpool. I don't know what a good level for 'healthy' is. Currently I've left about 1% (2GB) on a 200GB raid-z pool. -Brian -- --------------------------------------------------- Brian H.
