Lately on a shared host, the filesystem containing my home folder was mounted read-only for 45 minutes to 1 hour. The technical support did not know about the outage, evaded direct questions. After a bit more than three days I obtained the answer:
There are many explanations, but in the most times this caused by server issue on filesystem level.
I am somehow not pleased by this in-depth analysis, as my normal work environment runs on a RAID1 (
mdadm) and I never encountered such issues.
The shared host system is supposed to be a RAID1, and I became aware of the issue as a cronjob running uptime every 15 minutes sent me email about it.
I would really like to know, what you, the more experienced, think of this.
