Hello. TRIM command issued to SSD doesn't work with this mount options: ============================ rootfs / rootfs rw 0 0 /dev/root / ext4 rw,noatime,commit=100,barrier=0,nobh,stripe=128,data=writeback,discard 0 0 proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0 rc-svcdir /lib64/rc/init.d tmpfs rw,nosuid,nodev,noexec,relatime,size=1024k,mode=755 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 udev /dev tmpfs rw,nosuid,relatime,size=10240k,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620 0 0 shm /dev/shm tmpfs rw,nosuid,nodev,noexec,relatime 0 0 ============================ Removing "data=writeback" option from /etc/fstab and from rootflags in kernel boot options results in TRIM working just like it should. So, the question is: Is this "data=writeback" and TRIM incompatibility a bug or a feature? :) Thank you.
