ls -l /dev/disk/by-id/ deve fazer o truque
Se eu executo o iostat, vi isso:
avg-cpu: %user %nice %system %iowait %steal %idle

dm-2 647.62 383.52 5009.47 22333866 291722528
Parece que dm-0, dm-2 é o culpado. O mais provável é que a leitura seja transformada em gravação porque a iotop mostra:

Meu fstab é isso:
/dev/mapper/VolGroup-lv_root / ext4 usrjquota=quota.user,jqfmt=vfsv0 1 1
UUID=1450c2bf-d431-4621-9e8e-b0be57fd79b6 /boot ext4 defaults 1 2

tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0

/dev/sdb1 /home2 auto auto,defaults 0 0
/dev/sdc1 /home3 auto auto,defaults 0 0
/dev/sdd1 /home4 auto auto,defaults 0 0
O problema é qual deles é dm-0, dm1 e dm-2? Eu suponho que vou apenas alterar os padrões para padrões, relatime, mas quais linhas?
se eu fizer ls -l / dev / disk / by-id /
Eu tenho
lrwxrwxrwx. 1 root root 10 Dec 26 05:03 dm-name-VolGroup-lv_home -> ../../dm-2
lrwxrwxrwx. 1 root root 10 Dec 26 05:03 dm-name-VolGroup-lv_root -> ../../dm-0
lrwxrwxrwx. 1 root root 10 Dec 26 05:03 dm-name-VolGroup-lv_swap -> ../../dm-1

Existem 2 entradas para / dm-0 a dm-2. Eu quero saber porque. Eu suponho que eu tenho o que preciso por agora. Como eu suspeito, a troca não é o problema. Root e home é o problema que é meio estranho, já que todas as contas em / home já foram movidas para outro lugar.
