Hello All, First of all I want say thanks for all the info I see every time in this list. Second, sorry for my basic english. I writting this because I'm experiencing an issue with a Centos over a VPS. Every saturday (I have installed this vps since 3 weeks ago) I check the status of the server I found that the file system is in read-only mode #touch test touch: cannot touch `test': Read-only file system # mount -o remount / mount: block device /dev/sda1 is write-protected, mounting read-only Looking for info in the logs, I don't know how to get the root cause of the issue. But I can see that the last writing process is marked about the 1:40 hr #ls -ltr - /var/log -rw------- 1 root root 479825 Sep 13 01:20 maillog -rw------- 1 root root 229268 Sep 13 01:30 cron -rw------- 1 root root 106941 Sep 13 01:34 messages (now is Sep 13 18hr) The centos is mounted on a VPS. The VPS server is a Proxmox. The sysadmin of the VPS told me that there is a backup process running on friday at midnight. I suppose that the issue is a very high I/O request on the HD during the backup process. ( example in vmware http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=51306 ) # uname -a Linux 2.6.18-371.12.1.el5 #1 SMP Wed Sep 3 16:22:34 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux There is any kind of workarround for this (make the centos more flexible about the I/O timeouts or fails) Or maybe there is something to recommend to the VPS sysadmin to solve this issue? more info: # more /etc/fstab LABEL=/ / ext3 defaults 1 1 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 LABEL=SWAP-sda2 swap swap defaults 0 0 #df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 19G 3.4G 15G 19% / tmpfs 502M 0 502M 0% /dev/shm The previous times it happened the fsck after a reboot fixed the issue. Thanks in advance. PP
