Thank you all Since all concerns were about reliability I am assuming performance impact of having OS running on SD card is minimal / negligible
In other words, an OSD server is not writing/reading from Linux OS partitions too much ( especially with logs at minimum ) so its performance is not dependent on what type of disk OS resides on If I am wrong, please let me know :-)) Thanks On Wed, 15 Aug 2018 at 04:13, Janne Johansson <[email protected]> wrote: > > Den ons 15 aug. 2018 kl 10:04 skrev Wido den Hollander <[email protected]>: > >> > This is the case for filesystem journals (xfs, ext4, almost all modern >> > filesystems).
