@andrew_cb said in Another Netgate with storage failure, 6 in total so far:
For example, if a log file is written every 1 second, then in the span of 5 seconds there could be 640 KB (5 x 128 KB blocks) of data to write, just for that single log file.
Maybe, but it could also be one block if all updates fit into the one block. (there is also compression)
(Edit: 5 updates to one log file, or to 5 log files)
Note the amount of metadata changes with recordsize (there are more blocks per file), as do things like write speed.
It stands to reason though most of the writing on pfSense is log files, or periodic file updates like pfBlocker feeds.
