I looked into this two years ago and found that although insertion/removal appeared to often work, in particular with scsi, it was not really officially supported thru the entire protocol stack at the time. Now, I find evidence in general, hotplug support has improved, presumeably positively influenced by subsequent USB and firewire development. But disks are more complex than printers, scanners, etc so Im having a difficult time forming an opinion about how "official" this all is for disk storage. Have the improvements gotten into disk storage related areas also? Should I really consider relying on hotplug disk storage in a mission critical application? Well, I would really be interested in any comments anyone had, privately or publicly, on the maturity of hotplug disk storage in Linux 2.4. Does insertion/removal of existing/new devices work reliably on IDE, SCSI, Fibrechannel, USB, iee1394? Is it "officially" supported? Are you using it on a mission critical machine? Do things like the MD driver and LVM handle hotplugged drives reliably well? Of course I assume appropriate hardware doing the right things electrically and that any filesystem is unmounted. Any help understanding the current state would be greatly appreciated! Thanks, Mark sfhotplug@feldmark.com P.S. Ive looked thru the LDP, google, and elsewhere with little luck; apologies that I can't look at the home page for the hotplug project because I am in China, and all sourceforge project home pages are blocked. sigh..... ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
