February 1Feb 1 Dear Unraid Community,Out of nowhere, my cache pool and some shares become read-only.This is the second time I face such issue. First time I though it just some hiccup and and I reformat the cache pool drives and recover the filesystem. But this happened to me again.I would like to find the root cause. Would you please help me and direct me, what should I check first?I am attaching current diagnostics:.tower-diagnostics-20260201-1551.zip
February 2Feb 2 Community Expert Solution Btrfs is detecting data corruption in all the disks and pososl. My recommendation would be to first run memtest.
February 11Feb 11 Author @JorgeB you were right. Thank you.I have run the memtest and it got failed after couple of seconds. I swap the memory modules between slots to be sure is the memory module and not the socket or something else. One of the module was failing. I'll send it back to warranty but keep an eye how the system stability looks now.Do you know any tools to be notified once some corruption occur in the system. Does the scrub do the job? If yes, how often do you recommend to run it?
