<div dir="ltr">As I had some trouble on my recording storage (JFS/LVM2/RAID5), I decided to recreate my storage with a ext3 fs on raid5 (mdadm).<br>I know that ext3 isn't the most efficient filesystem for this purpose, I don't want to use JFS anymore and I also read some messages talking about trouble with XFS.<br>
<br>I think it is quite difficult to align ext3, lvm2 and mdadm for best performance, so I choose to give up using lvm2.<br><br>Which is the best chunk size for arrays ?<br><br>For ext3 creation, <a href="http://tldp.org/HOWTO/Software-RAID-HOWTO-5.html#ss5.11" target="_blank">http://tldp.org/HOWTO/Software-RAID-HOWTO-5.html#ss5.11</a> mention setting --stride option.<br>
<br>I also know about<br>-T largefile4 and -T largefile for big files<br>-m 0<br><br>Another thread has been initiated on <font color="black" face="Verdana,Arial,Helvetica" size="2"><font color="black" face="Verdana,Arial,Helvetica" size="2">"optimal ext2fs formatting for recordings"<b> </b></font></font>(<a href="http://www.gossamer-threads.com/lists/mythtv/users/347878">http://www.gossamer-threads.com/lists/mythtv/users/347878</a>) but doesn't focus on creating ext3 fs on raid5.<br>
<br>Is there other options I should set ?<br><br>Kind regards.<br></div>
