[Gluster-users] total outage - almost

[Bernhard Dübi]

Hi,

I checked the attributes of one of the files with I/O errors

root at chastcvtprd04:~# getfattr -d -e hex -m -

the "dirty" is 0, that's good, isn't it?
what's the "trusted.bit-rot.bad-file=0x3100" information?

Best Regards

BTW: I saved all logs, maybe I can upload them somewhere
