Re: OpenBSD File systems , on Flash / SSD CPE (in sites with uncontrolled power (CPE customer sites)

We had a similar challenge. My advice would be to leave all the filesystems as is - and add the 'sync' flag. It slows down disk access - but makes the filesystem resilient to power outages. See sync option - https://man.openbsd.org/mount On Tuesday, 29 November 2022 at 09:03:28 am AWST,

Re: OpenBSD File systems , on Flash / SSD CPE (in sites with uncontrolled power (CPE customer sites)

Hi, In the case of CPE, I do not think that programs will be added or removed after the start of operation, so I think that the following partition can be mounted as read-only to reduce the impact of power failure. /bin /sbin /usr /usr/local (with wxallowed) For the rest, you can just mount

sorry there was an omission in my /etc/fstab i had left out the softdep,noatime flags on the filessytems that were funning off the disk using FFS Thanks #begin corrected /etc/fstab## /dev/sd0a / ffs rw,softdep,noatime 1 1 /dev/sd0d /usr/local ffs

Hello, Folks, Im reviewing our filesystem setup for OpenBSD CPEs that we deploy in the field in order to minimise the impact of Power Outages / Customer interference on the boxes, we install a 4G root partition / and a 2GB /usr/local (to allow the wxallowed flag for the filesystem) we use mfs

You should reboot whenever patches or upgrades require it. Was that a trick question or something? On Mon, Nov 28, 2022 at 12:51 AM Greg Thomas wrote: > > > On Sun, Nov 27, 2022 at 12:08 PM James Johnson > wrote: > >> Thank you for this interesting perspective. >> >> Combined with the
