mount option stripe not defined in fstab

I have an AWS instance.

Suddenly I can see this new mount option stripe=32736

/dev/xvdb on /var/lib/elasticsearch0 type ext4 (rw,relatime,stripe=32736,data=ordered)
/dev/xvdc on /var/lib/elasticsearch1 type ext4 (rw,relatime,stripe=32736,data=ordered)

But this option not appears in fstab

root@thorin:~# cat /etc/fstab

LABEL=cloudimg-rootfs   /       ext4    defaults,discard        0       0
/dev/xvdb       /var/lib/elasticsearch0 ext4    defaults        0       0
/dev/xvdc       /var/lib/elasticsearch1 ext4    defaults        0       0

So, I have two questions.

  1. Why have this happend?
  2. How can I fix this?

Some time ago I fix this in another machine. I was something related with RAID headers. There was some tool to set stripe to 0 but I can't find this now.

Solution

  • I can answer second question.

    tune2fs -f -E stride=0 /dev/xvdb
