[-- Attachment #1 --] Following up on the discussions during EuroBSDCon 2015 (Stockholm) during the FreeBSD Developer Summit regarding various ZFS configuration settings, I write to start our implementation phase now that some usual suspects have joined the list. re https://wiki.freebsd.org/201510DevSummit/Performance I think the first order of business is granting access rights to the server (varm) in question: http://dan.langille.org/2015/07/19/varm/ During the workshop, mention was made of serial access. I can arrange that. The server has IPMI, however, my first thought: 1 - connect a USB-serial cable to varm & link that to another server in my rack. 2 - create a jail in that server and give it access to that serial connection 3 - redirect incoming port XYZ to that jail via a public-key-only ssh connection 4 - give people access Any suggestions? — Dan Langille http://langille.org/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQJ8BAEBCgBmBQJWG+cdXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ1MTE2RjM0ODIzRDdERDM4OTY0OUJBNzdF QjIxNTlERUU5NzI3MzlGAAoJEOshWd7pcnOfoFkP+gOAZGf4TVHqPq0wPwPXP/82 kMwfUj9Mj6yD2c5u7vdKT1DPHXWBcmWd9Wqv8zDoJQw/C+K0gRykMcNDyVkJpQU0 vY7njBk4I287IiH7d1vRoFxvQxCLKNl/unladjwzaRylCVFiGzFhGHX3F2iZSuDn it2UzbCZuqLNvJvO8nNuhl/oe/ZYq3nomBAt+KAhuLnMQAqEmUTu3YV5JGRegve7 9kpTzZRgncvzPDHoiBd8VUfIgvd9gQFm3+bjf8EEkkeKfshcOkCU/5AUA7j41Tsb 7pUSY5ZCcvsULYmcu9ebK5myE04k9tdb3gXU2amB8BAbQFT9rBLdajzM8rcHyFob Mblv2e2b/HikRMYyRTHN9Zc+BQ1XokakyStzbmXaaVrLeMlRMD74DgAGfRTKmFbD dAzY+rjzEnddfteNZDgX0Coqa4WaUIii4hMlgPou+Vc/O2FpqnJGVt1Qgqr+KPH6 HuNY5vVpCKcTn+LPmqhWlCXZl5fUvZwdAm9dGx5YS3yTcU2P89F/rDQWeaDzxXhM Nee5lfZpsZnjUZOYFTzb3qcJzmNTE6M79yhxZ59ibetE8w03Mga4EnNzMBdeoq6f xXcN10lVqQwICNkmJCbQClzXPC7UFsclihvbgha931JJCmZlzpokJYhpa6RF0t+y DjUOeDPhopWR3vmPzK8c =iOs1 -----END PGP SIGNATURE-----help
