Hi,

I had a look today for the first time in the full system log (using the Expert mode(Openwrt)), and I have seen that periodically and most often after each scheduled database backup to a Fat formatted USB key plugged on the front USB socket) the following warning is logged : FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

The warning is logged also at times where no backup is performed. For instance, today, the backup was performed at 11h00, and I had the following warnings :

Code: Select all

Thu Jan  3 11:00:04 2019 kern.warn kernel: [355643.320000] FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
Thu Jan  3 12:43:10 2019 kern.warn kernel: [361828.760000] FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
Thu Jan  3 12:43:28 2019 kern.warn kernel: [361847.170000] FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
Is there something I should worry about ?

Thanks

Jacques

This happens when you pull a USB stick before having the filesystem unmounted. Usually nothing bad happens when you are on a FAT32 system.

This message is just about your external USB stick, internal is not affected.
