Ah, that sorted things out for me as well. I did get a "kmem_malloc(X): kmem_map too small: Y total allocated"-panic, is that still something that should be ignored? It also looks like 'zpool list' shows the wrong(?) size and available info if showing a raidz-pool: (ad1-3 512MB disks) # zpool create test raidz ad1 ad2 ad3 # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT test 1.48G 157K 1.48G 0% ONLINE - # df -ht zfs Filesystem Size Used Avail Capacity Mounted on test 980M 32K 980M 0% /test # dd if=/dev/random of=/test/temp bs=1M count=512 512+0 records in 512+0 records out 536870912 bytes transferred in 40.188660 secs (13358766 bytes/sec) # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT test 1.48G 773M 747M 50% ONLINE - # df -ht zfs Filesystem Size Used Avail Capacity Mounted on test 980M 515M 466M 53% /test It could be argued that it shows the correct amount that is consumed with redundant information, but when using a mirror instead, output is more as expected: # zpool destroy test # zpool create test mirror ad1 ad2 # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT test 504M 88K 504M 0% ONLINE - # df -ht zfs Filesystem Size Used Avail Capacity Mounted on test 472M 32K 472M 0% /test It could be that this is how it should be, but I think it is a bit confusing, it could also be that it is fixed in perforce, but I couldn't find anything in the log or found out how to check out a recent copy of the code. Thanks for the brilliant work on porting zfs, keep it up! -- Ståle Kristoffersen staalebk@ifi.uio.no
