<div dir="ltr"><p class="">Hey all,</p>
<p class=""> </p>
<p class="">I’m using XFS on a Ubuntu 14.04.1 x84_64 machine and
getting kernel oops messages from the XFS module almost daily.</p>
<p class="">My machine is a 6-core Core-i7 with 24GB RAM, an mdadm
software raid5 over 4 disks with an XFS fs on it.</p>
<p class="">Here is a typical error message:</p>

I use it for backup and noticed that each backup from the main array to the second one used to take a long time and gave these errors. I switched from XFS to ext4 and not only did the errors go away (obvisouly...) but the backup time went down from almost 23 hours to 1 hour!</p><p class=""><br></p><p class="">Thanks,</p><p class="">Tal</p></div>
