-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone, I been using CF cards for almost more then 7 years now with ext file-system without any major problems on ALIX boards. Last year I took 30 other systems in production with ext4 and the CF cards been dropping out pretty fast, it may have been a bad batch but I do want to look at it. I don't think the devices writes a lot of IO (is there a tool that can give me some useful numbers for say 24H or a week? iotop, atop, sysstat doesn?t seem suited for long term IO write monitoring, but maybe I am misusing them and can use some help here) I mount root with the following options: /dev/disk/by-uuid/09a04c01-64c6-4600-9e22-525667bda3e3 on / type ext4 (rw,noatime,user_xattr,barrier=1,data=ordered) # dumpe2fs /dev/sda1 http://paste.debian.net/hidden/e3f81f11/ Are there kernel options to avoid synchronous disk writes? As suggested here: http://www.pcengines.ch/cfwear.htm Is there a list of other kernel options I can optimise to limit any cf wear? The devices don't use Kind regards Jelle de Jong -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iJwEAQECAAYFAlQ1ZhgACgkQ1WclBW9j5HmulgP9Fayd7V9t7bRgLo6NmjDVZoDM f+kH54/EnjsRfoKYYZDSO38WlwBWqJ1cFc+w2W2PMWKqJiL7QNk2+qMsSFeTCtLq JTz/e2ItLNqFJTAtX0bROgbEmNubfLQyvli+q/HspeSHGKKHjBzHelv5PDBciQCm vJEVwtB3Vb22hsWfSmw= =oCCY -----END PGP SIGNATURE----- _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
