subfs/submount and reiserfs: heavy remounts
Last modified: 2006-01-03 19:26:35 UTC
If you add a reiserfs (3.x) formatted USB disk, the hotplug system is mounting the disk, and a konqueror window is popping up. If you try to navigate/click in this window, the system is busy trying to mount the disk over and over again. This error is mentioned in other bug reports, but is is _not_ related to the "sync" problem. Its a problem of its own. Maybe a kernel interaction of subfs and reiserfs. IMHO, we don't need the submount functionality of trying an automatic mount every time a directory in /media is accessed. Instead, mounting should be triggered only by the hotplug scripts, and a timed auto-sync should protect us from data loss at device removal. Unmount should be done by the hotplug functions.
Kay, can you help debug what is happening here? If it's just subfs breakage feel free to reassign to Adrian.
Yes, it's a "feature" of subfs and a known issue. It has the same problem with other filesystems too. We see the same behavior for optical drives too. For 10.1 we can hopefully provide a way to configure problematic devices not to use subfs.
yes, reiserfs is anyway not designed to be used on removable medias, so we did ignore this for now
"reiserfs is anyway not designed to be used on removable medias" Adrian, can you explain this? I am using reiserfs for an external USB backup HD, and it's working fine (beside the subfs issue). I don't mind if this bug is not *fixed*. However, as Kay said, I hope you find a better solution than subfs for this hotplug issue in Suse 10.x.
