This bug was sent while the UI was still hung. I will let it run no more than two hours. Do'h! Logical volume was still mounted when I attempted to migrate extents. Target raid physical volume is 1.2T in size, original is 320gb. Target raid had not finished synhcronizing. No obvious errors found by grepping /dev/log. Logical volume has only one filesystem. No more then 43gb is in use on the entire filesystem, so it was 96% empty. It ran for 6 hours without updating the UI then completed successfully. I logged off, launched the app again. The UI freezes on piratically all lengthy tasks. You are right, UI waits until commands are finished. This is not a problem for lvdisplay, ... but lengthy tasks should be obviously handled in different way. This is surely valid request but s-c-lvm is going to be replaced by This feature is not critical and cannot cause data corruption, so it won't be fixed. System-config-lvm is obsolete tool and is being replaced by other tools. |
Description of problem: Attempting to migrate extends from physical volume on/dev/md127 to physical volume on /dev/md0 Both are two-disk software raid-1 volumes that are part of a single volume group. No other options were selecten in the "Migrate extents" dialog, but the entire UI freezes when "OK" is clicked. Frozen means that it does not even repaint when another window covers a system-control-lvm window. Looks like a death or blockage of the event thread. Version-Release number of selected component (if applicable): Unknown, UI is frozen. How reproducible: Once, so far. Steps to Reproduce: 1. Select physical extent 2. Click the "Migrate extents" button 3. Click "Ok" Actual results: UI Fails to respond or repaint. Expected results: Progress dialog appears. Additional info: pmove is running, as shown by "ps xua": /sbin/pvmove --config log{command_names=0} --alloc normal /dev/md126:0-76309
