Dear, we are studying the possibility to migrate our FS in the next year to cephfs. I know that it is not prepare for production environments yet, but we are planning to play with it in the next months deploying a basic testbed. Reading the documentation, I see 3 mons, 1 mds and several ods's (both in physical machines..I have understood). Is this true? On the other hand I do not understand the fail-over mechanism for clients when have mounted a FS, looking at documentation :
*ceph-fuse* [ -m *monaddr*:*port* ] *mountpoint* [ *fuse options* ] You have to specify (hardcode) the "*monaddr*: *port", if this mon (ip) is down, what happen, Do you lost the fs on that node?, or there is a generic dns-rrd implementation for mons?? * * Is there any implementation for "tiering" or "HSM" at software level, I mean, can I mix different type of disk (ssds and SATA) on diferent pools, and migrate data between them automatically (most used, size, last time access) * *Please could anyone clarify to me this point?* *Regards, I* -- #################################### Iban Cabrillo Bartolome Instituto de Fisica de Cantabria (IFCA) Santander, Spain Tel: +34942200969 #################################### Bertrand Russell: *"El problema con el mundo es que los estúpidos están seguros de todo y los inteligentes están llenos de dudas*"
