Dear freebsd-fs, As I am trying to install a new small server with a most partitions on ZFS, I am running into some little read-only troubles. At boot the root is always set to read-only. The rest of the system is fine though: # zfs get all | grep readonly zroot readonly on temporary zroot/tmp readonly off inherited from zroot zroot/usr readonly off inherited from zroot […] I cannot seem to understand what may cause this issue. The system is a typical manual [1] installation (used to work fine), on an empty system. Note that I can reset the root to readonly=off with: # zfs set readonly=off zroot but it is a pain to to it manually without understanding why. I also cannot seem to get much info from the log messages: ==> /var/log/messages <== Feb 18 18:56:24 kernel: Root mount waiting for: usbus4 Feb 18 18:56:24 last message repeated 2 times Feb 18 18:56:24 kernel: uhub4: 8 ports with 8 removable, self powered Feb 18 18:56:24 kernel: Root mount waiting for: usbus4 Feb 18 18:56:24 kernel: ugen4.2: <vendor 0x058f> at usbus4 Feb 18 18:56:24 kernel: uhub5: <vendor 0x058f product 0x6254, class 9/0, rev 2.00/1.00, addr 2> on usbus4 Feb 18 18:56:24 kernel: uhub5: 4 ports with 4 removable, self powered Feb 18 18:56:24 kernel: Trying to mount root from zfs:zroot [rw]... Feb 18 18:56:29 kernel: . Feb 18 18:56:30 kernel: . There are a couple of mentions to this same problem in 2012 on this mailing list [2] and on an unanswered forum message [3], but they did not solve the issue (setting vfs.root.mountfrom.options=rw only changes the log message). The machine starts its other services (such as SSH) correctly though. Hope someone will have an idea.
