My fstab= ext4 noatime,errors=remount-ro 0 1 I read through the solid_state_drive arch link and I think I should check my logs for errors.
I checked the /etc/cron* dirs and saw no fstrim cron.weekly job. That's weird because I thought ubuntu defaulted to a cron.weekly fstrim job. Now, I'm wondering whether the install knows the install drive is a SSD?? I looked on this 16.04 box (M.2 ssd as well, w/no issues) and I have a cron.daily and cron.weekly jobs for fstrim! I guess I should fix that. I manually ran the fstrim on the 18.04 box w/issues the other day and saw 211 Gb trimmed. Just now, I ran it again and would guess that it has been running idle for 7 or 8 hours: $ sudo fstrim -av [sudo] password for don: /: 211 GiB (226551054336 bytes) trimmed Thanks, Don On 06/15/2018 01:04 AM, Ralf Mardorf wrote: > On Thu, 14 Jun 2018 17:06:40 -0400, Daniel Wastak wrote: >> UUID=[Your blkid here] / ext4 noatime,errors=remount-ro > I'm using "noatime" for partitions used to record realtime audio, but > for anything else I stay with the default "relatime" for good reasons, > see the mount manpage. > > [weremouse@moonstudio ~]$ lsb_release -d; man mount | grep 'relatime' -A2 | > tail -11 | head -3 > Description: Ubuntu 16.04.4 LTS > relatime > Update inode access times relative to modify or change time. > Access time is only updated if the previous access time was earlier than the > current modify or change time. > (Similar to noatime, but it doesn't break mutt or other > applications that need to know if a file has been read since the last time it > was modified.) > > I recommend to take a look at the Arch Wiki.
