Anyone know about jmicron_raid_member filesystem?
Linode are telling my backups are failing because I am trying to backup a jmicronraidmember filesystem. It failed a few days ago.
Thing is, I have not done anything on the server. I have not added this. The server has been for a very long time a standard CentOS install on an ext3 filesystem, using Webmin and Virtualmin to manage it, I use it for emails and one web application. I have had it up for quite some time now, maybe a year or so, no problems, backups always worked. Then a few days ago I was told this jmicronraidmember filesystem exists and backups failed.
The server has not had any downtime for this jmicronraidmember to be introduced.
So I wondered if anyone knows anything about this filesystem, where it comes from/how its introduced. If it can be introduced with no downtime, why cant we reverse it with no downtime (Linode are saying I need to create a new server and copy data from this to the new one).
How does one find this listed? Its not listed in Linode Manager or on the server anywhere using fdisk/dh
Thanks!

So this following command does show the wrong filesystem, even though its not shown anywhere else:
[root@mail ~]# blkid
/dev/xvda: TYPE="jmicron_raid_member"
/dev/xvdb: UUID="b3fda3b3-028c-433b-acc3-9c62cb315036" TYPE="swap"
ext3 showing up OK with the following:
[root@mail ~]# mount
/dev/xvda on / type ext3 (rw,noatime,grpquota,errors=remount-ro,usrquota)
/proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,noexec,nodev)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
[root@mail ~]# df -T
