I reformatted it to ext4, and it's been much more robust. I never had that problem with XFS on drives mounted in a computer, but it was too fragile a filesystem to use on a device which could be accidentally disconnected or powered off. I have one that I had formatted with XFS it fell over if I looked at it funny. Some filesystems are more fragile than others on external drives. You should also use "safely remove" if it's a USB device. If you must disconnect the external drive from some reason, umount the filesystems on it first. If the device is an external drive of some sort, chances are it wasn't unmounted properly some time in the past.

Browsing through /var/log/syslog and /var/log/messages might help, too. First find out why the OS was only willing to mount the filesystem read-only.

Sudo mount -n -o remount,rw /dev/sda1 /mnt/pointīut that's a last-ditch effort. You can force the system to remount the filesystem in read-write mode by using the command: Then try mounting it again and see if it's still read-only. You'll need to unmount it and run something like 'fsck /dev/sda1' to fix the errors.

That's what usually results in a "read-only file system" error. No dice.It's likely that the filesystem has errors and was mounted read-only by the operating system. The idea was to replace the drive that was throwing a bunch of SMART errors after the reboot. All I did was reboot because of a copy error from the QNAP to external drives we hooked up for backup. Is there anything I can be doing or saying to QNAP support to move things along? Is it pretty normal for a file system check to take weeks with this large of a dataset? It's a purely internal project so not the end of the world if we lose those clips, but I'd love to keep them obviously. We use this as one of two backup targets for our main array, but our main array is all flash based and one of our projects is 16TB on its own (whole QNAP is 57TB full out of 64TB) and it was just a perfect storm of moving things around and not having a second copy of a few recent bits we filmed. It's a QNAP TVS-1282T3 with 8 x (now 7x lol) 12TB Ironwolf Pros in a RAID 6. To top things off one of the disks degraded and pulling it did nothing to help with the file system check speed. The unfortunate thing is that I was in the middle of running a fresh backup of a project that I only have about 90% of. I've had a ticket open with QNAP support since 6/15 and they've had a remote connection via ssh to run a file system check, however it has been running for the past two weeks without any kind of real update.
