Description of problem: I cant eject my usb driver because device is busy. The following processes running, and I get an error message when I try to safety remove. /usr/libexec/udisks2/udisksd # 6 process /usr/libexec/gvfs/udisks2-volume-monitor # 4 process Version-Release number of selected component (if applicable): Up to date Fedora 37. Usb 3.1 drive with exfat. exfatprogs: 1.2.0 How reproducible: I dont know. Its a 128GB usb drive. I can mount, and can move/copy files. but currently: Nautilus: - Only "Eject" option: Unable to eject: Error ejecting /dev/sdb: Command-line `eject '/dev/sdb'' exited with non-zero exit status 1: eject: cannot open /dev/sdb: Device or resource busy. /dev/sdb1 not mounted. When I click to usb drive again, mount to /run/media/my_user/Drive_NAME Disks: - "Eject this disk": Error ejecting /dev/sdb: Command-line `eject'/dev/sdb'' exited with non-zero exit status 1: eject: cannot open /dev/sdb: Device or resource busy (udisks-error-quark, 0) I mount again. - "Power of the disk": Error powering off drive Error opening /dev/sdb for fsync: Device or resource busy (udisks-error-quark, 0) Actual results: Umount success, but Nautilus does not say: remove is fafety. When I click again to eject, drop: Error ejecting. Expected results: Safety remove. driver Additional info: Usb drive is an exfat. I moved and delet some large and small files from this device. My device is healthy. I check it with fsck.exfat, and show no error: sudo fsck.exfat /dev/sdb1 exfatprogs version : 1.2.0 /dev/sdb1: clean. directories 3070, files 24516 udisksctl power-off -b /dev/sdb1 Error powering off drive: Error opening /dev/sdb for fsync: Device or resource busy (udisks-error-quark, 0) udisksctl power-off -b /dev/sdb Error powering off drive: Error opening /dev/sdb for fsync: Device or resource busy (udisks-error-quark, 0) lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 465,8G 0 disk ├─sda1 8:1 0 150M 0 part /boot/efi ├─sda2 8:2 0 512M 0 part /boot ├─sda3 8:3 0 457,1G 0 part / └─sda4 8:4 0 8G 0 part [SWAP] sdb 8:16 1 117,9G 0 disk └─sdb1 8:17 1 117,9G 0 part sr0 11:0 1 1024M 0 rom zram0 252:0 0 8G 0 disk [SWAP] mount proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime,seclabel) devtmpfs on /dev type devtmpfs (rw,nosuid,seclabel,size=4096k,nr_inodes=1048576,mode=755,inode64) securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,seclabel,inode64) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,seclabel,gid=5,mode=620,ptmxmode=000) tmpfs on /run type tmpfs (rw,nosuid,nodev,seclabel,size=3257464k,nr_inodes=819200,mode=755,inode64) cgroup2 on /sys/fs/cgroup type cgroup2 (rw,nosuid,nodev,noexec,relatime,seclabel,nsdelegate,memory_recursiveprot) pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime,seclabel) efivarfs on /sys/firmware/efi/efivars type efivarfs (rw,nosuid,nodev,noexec,relatime) bpf on /sys/fs/bpf type bpf (rw,nosuid,nodev,noexec,relatime,mode=700) /dev/sda3 on / type ext4 (rw,relatime,seclabel) selinuxfs on /sys/fs/selinux type selinuxfs (rw,nosuid,noexec,relatime) systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=35,pgrp=1,timeout=0,minproto=5,maxproto=5,direct,pipe_ino=1668) hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime,seclabel,pagesize=2M) mqueue on /dev/mqueue type mqueue (rw,nosuid,nodev,noexec,relatime,seclabel) debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime,seclabel) tracefs on /sys/kernel/tracing type tracefs (rw,nosuid,nodev,noexec,relatime,seclabel) fusectl on /sys/fs/fuse/connections type fusectl (rw,nosuid,nodev,noexec,relatime) configfs on /sys/kernel/config type configfs (rw,nosuid,nodev,noexec,relatime) tmpfs on /tmp type tmpfs (rw,nosuid,nodev,seclabel,size=8143656k,nr_inodes=1048576,inode64) /dev/sda2 on /boot type ext4 (rw,relatime,seclabel) /dev/sda1 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw,relatime) tmpfs on /run/user/1000 type tmpfs (rw,nosuid,nodev,relatime,seclabel,size=1628728k,nr_inodes=407182,mode=700,uid=1000,gid=1000,inode64) gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000) portal on /run/user/1000/doc type fuse.portal (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)
