--FFoLq8A0u+X9iRU8 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I've used ZFS on my main desktop since it became available but I've never= =20 gone for zfs-on-root. For maximum flexibility I have the OS installed on SSD UFS and homedirs/dat= a=20 on zfs. Presently there's 2x mirrors but it was a raidZ1 array at one time. I've had the SSD go bad so have simply replaced it, installed latest freebsd-12 from usb stick, then zpool imported my pools. I use zfs for the data I care about if it gets mangled. So config files backups go there as well. But such data doesn't need to be accessible very quickly, it just has to be fast enough. I've always known there'll be a performance penalty beca= use zfs does so much stuff, I'm not using high-end hardware, so for me it doesn= 't make sense to use zfs for the OS. Another point, you might want to make sure your cluster size for your pool = is the native size for your disks. If they're mismatched it can result in poor= er disk i/o. --=20 J. --FFoLq8A0u+X9iRU8 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAl5C2TEACgkQs8o7QhFz NAX+0g//dyj/jXdGPIHci5VZTtsjrhKS5IpHAhqBq4rk86yTgvGBNrchvLq7ctrm yGmM85kAfpHzhYkAboibKpjw1REClQ4oBB1y4Qqy1rshY6ubejW0S/VEiUCy5I7G Q/wTaVFCsvtDsyidHMbDr3oMkOlbEAt8ow2a0/cGP9U8RBNJCDevxpb7s7gm1z8Q 0uI6/pIjK6Usn26vd+UPF4A+BM/aU2h1MV7n395iOO1nidpAzmS9j/r6eRZtkNG4 XJohP1gJxt8yKt9JR14A5+dy9BRBVpVe09g5ae4vy0Ny3SWDknWtCoDcNCmS0omu OtBo1qibUuM79+IS174mkMyV0hqHkNVOzraQsINW2MMTtX6fMnOIYKwRLnPKGkq5 h5KFSXfZi8mgP5YckXtf4dhYWZ42dlmk9O0xXww07gViSeiByQtZCtc/GCMgdFLH TCzt8TcGftDYe1pnHfGNt1LlPxhRQZGvjtguW++sdZnsRvmwCJof2Ss85MCr9kwb 1vH96bl7J1X95Qim2aNmfoZ5It37Y5sDo+qRtj5Z+VfVYuu7wcqxW2o+Y4TduN0v /o+y6UK840/Wjwv60HviOce6h4/fCRR0BuGN/vEjEjWI8bn1jN9sYl2lLdHWCdtG BNgoe5TYJTNdwF0VdbkSNyPGzCh/a9dI7t4AyPmtLek6Xw2TVPc= =eHBl -----END PGP SIGNATURE----- --FFoLq8A0u+X9iRU8--
