Remedyz.boston is J5's box. Anyway, it's completely safe to yank a mounted USB device, as far as system is concerned. If someone disagrees, we'll meet at dawn. :-) Your data on it may suffer, but hey, that's called "freedom" (to hurt yourself). Current VFS orphans necessary files and inodes just fine in case of a forced umount. Even if there was no umount, ub correctly orphans the block device (actually, I think usb-storage and sd_mod try too). So you are "guaranteed" that the system won't oops. What is left is the filesystem integrity and delayed writes. Mounting with "sync" is harmful and slow, but I think we do not delay writes these days. So, it should be safe to look at LEDs and pull the device when they stop flashing. Seriously, people, USB devices are designed to be hotpluggable. -- Pete -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
