Jim, This makes sense. fmdump -eV reported that your original drive was experiencing repeated fread failures ( scsi command code 0x28) Steve - Original Message - Well, I decided to bite the bullet and kick the original disk from the pool after replacing it with the spare, an

Re: [zfs-discuss] arc_no_grow is set to 1 and never set back to 0

The interesting bit is what happens inside arc_reclaim_needed(), that is, how it arrives at the conclusion that there is memory pressure. Maybe we could trace arg0, which gives the location where we have left the function. This would finger which return path arc_reclaim_needed() took. Steve

[zfs-discuss] ZFS p[erformance drop with new Xeon 55xx and 56xx cpus

As I am looking at this further, I convince myself this should really be an assert. (I am running release builds, so assert-s do not fire). I think in a debug build, I should be seeing the !list_empty() assert in: list_remove(list_t *list, void *object) { list_node_t *lold = list_d2l
