Jes, I know there are fixes queued for Intel Software RAID somewhere. Eric, the fs in question is ext4. You guys can duke it out... FIGHT! Peter, Does this also happen after you updated to dracut-017 as you reported in BZ#752593? The problem with IMSM RAID is that if we get into the reboot hang stage, mdmon will not finish writing out the metadata to the RAID and you can end up with files not making it out to disk. If you can reproduce this with dracut-017 installed, then it is likely another problem. Thanks, Jes (In reply to comment #2) > Peter, > > Does this also happen after you updated to dracut-017 as you reported in > BZ#752593? No longer, it looks like that something was extended now, Alt-SysRq U for "readonly" now reports EXT4-fs (md127p1): remounted. Ops:(null) EXT4-fs (md127p8): remounted. Ops:(null) Alt-SysRq O for "off" displays now similar messages regarding RAID as on reboot. So the new dracut version fixes this issue - also after power-on BIOS *and* Windows reports the IMSM RAID as clean (which was not always the case in the past) Peter, This is good news! Sounds like the problem was caused by mdmon not managing to write out the metadata then. I'll close this bug, but if you see this problem again, please go ahead and reopen it. Cheers, Jes |
