USB is not writable... so sad.

HI.
I connected a usb disk before and all was fine.
But today i dont know what happen that is just read only..

root@pve:/mnt# mkdir share
root@pve:/mnt# cd ..
root@pve:/# mount -t ntfs /dev/sdb1  /mnt/share/
root@pve:/# cd mnt/share/
root@pve:/mnt/share# touch ho
touch: cannot touch 'ho': Read-only file system

what can i do?

I think you need to install ntfs-3g:

It could also be that your USB disk is dying.

It could also be that your USB disk is dying.

Unlikely, default PVE kernel only includes r/o NTFS support (see discussion here)

hi. Thanks.
I see that it is mounted like this:

/dev/sdb1 /mnt ntfs ro,relatime,uid=0,gid=0,fmask=0177,dmask=077,nls=utf8,errors=continue,mft_zone_multiplier=1 0 0

But, when i mounted i just did:

mount -t ntfs /dev/sdb1  /mnt/

But, when i mounted i just did:

those are defaults, you only need to specify them if you want to change the default values.
For example, you can try mount -t ntfs -o rw /dev/sdb1 /mnt/

Thanks. I try first to umount and it seems..... busy...
So, i try with

root@pve:~# umount -l /mnt

and then

root@pve:~# mount -t ntfs -o rw /dev/sdb1 /mnt/
mount: /mnt: /dev/sdb1 already mounted or mount point busy.
dmesg(1) may have more information after failed mount system call.
root@pve:~# umount -l /mnt
umount: /mnt: not mounted.


it says is mounted but... also say is not?

Well, the ntfs crap was dirty...
i use ntfsfix and it is fixed... im getting all the files, and one i have all the backups in other side i will format this usb disk (it is 1TB).
What would you think will be a good file system? i dont really care if just can be read from a Linux system.

Thanks!!!!!!!!!
(i can breath......)

ext4 should work fine, XFS seems slightly faster on the same hardware and is better for larger drives (but cannot be shrunk)

ZFS if you want compression, snapshots, easy SMB sharing and the like ( but you only get self-healing with a mirror or above, e.g. RAIDZx -- or you could try copies=2 per-dataset for critical data on a single-disk pool ) -- but make backups regardless
