Hi Folks, Over the past few days I've been troubleshooting some BRTFS errors that have appeared in my Syslogs. Previously, a simple restart would restore my ability to mount the filesystem and run my dockers, but as of this afternoon, the filesystem is unmountable. I've attached a diagnostic from this afternoon (21st) and yesterday (20th). From what I see searching online, it seems either there is an issue with a memory module which lead to some corruption issues or there is an issue with one of my drives. My cache setup is a RAID 1 BTRFS of an NVME drive and a SSD (in my logs, /dev/sdc1 and /dev/nvme0n1). Notably, on September 20th (Diagnostic attached), I see the following: Sep 20 00:45:28 Unraid kernel: BTRFS critical (device sdc1): corrupt leaf: root=5 block=1161025175552 slot=143 ino=20996272 file_offset=65536, invalid type for file extent, have 164 expect range [0, 2] Sep 20 00:45:28 Unraid kernel: BTRFS info (device sdc1): leaf 1161025175552 gen 1029363 total ptrs 197 free space 749 owner 5 Today, I see the following: Sep 21 04:03:17 Unraid kernel: ------------[ cut here ]------------ Sep 21 04:03:17 Unraid kernel: WARNING: CPU: 16 PID: 34855 at fs/btrfs/extent-tree.c:3061 __btrfs_free_extent+0x466/0xc02 Sep 21 04:03:17 Unraid kernel: Modules linked in: veth wireguard curve25519_x86_64 libcurve25519_generic libchacha20poly1305 chacha_x86_64 poly1305_x86_64 ip6_udp_tunnel udp_tunnel libchacha xt_CHECKSUM ipt_REJECT nf_reject_ipv4 ip6table_mangle ip6table_nat iptable_mangle vhost_net tun vhost vhost_iotlb xt_nat xt_tcpudp xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink xfrm_user iptable_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 xt_addrtype br_netfilter nvidia_uvm(PO) xfs nfsd auth_rpcgss oid_registry lockd grace sunrpc md_mod zfs(PO) zunicode(PO) zzstd(O) zlua(O) zavl(PO) icp(PO) zcommon(PO) znvpair(PO) spl(O) ip6table_filter ip6_tables iptable_filter ip_tables x_tables macvtap macvlan tap bridge 8021q garp mrp stp llc ixgbe xfrm_algo mdio e1000e nvidia_drm(PO) nvidia_modeset(PO) intel_rapl_msr intel_rapl_common iosf_mbi x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm nvidia(PO) crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel sha512_ssse3 video aesni_intel Sep 21 04:03:17 Unraid kernel: drm_kms_helper crypto_simd ipmi_ssif cryptd drm rapl isci i2c_i801 intel_cstate nvme backlight mei_me i2c_smbus ahci cp210x apex(O) libsas syscopyarea input_leds sysfillrect sysimgblt i2c_core joydev led_class usbserial mei intel_uncore nvme_core scsi_transport_sas libahci gasket(O) fb_sys_fops acpi_ipmi wmi ipmi_si button unix [last unloaded: xfrm_algo] Sep 21 04:03:17 Unraid kernel: CPU: 16 PID: 34855 Comm: kworker/u82:5 Tainted: P W O 6.1.49-Unraid #1 Sep 21 04:03:17 Unraid kernel: Hardware name: To Be Filled By O.E.M.

Any guidance on what I can look at next? The cache is currently unmountable -- do I have to format again and restore backups (appdata for Dockers, VMs), or is there a way to re-mount just a single (ex: the nvme drive) file system? If I do have to rebuild, I'm concerned I haven't found the root cause and will be back in this situation shortly.

This is definitely still an issue -- currently reading through past threads after upgrading to 6.10.2 and being flooded with the following messages and an unusable ConBee II: May 29 10:32:30 Unraid kernel: usb 2-1.4: usbfs: process 32050 (qemu-system-x86) did not claim interface 1 before use Solution as posted in this thread (and others) was to obtain the proper device path for the ConBee II and manually add this in to the virtual machine XML as per https://community.home-assistant.io/t/unraid-vm-conbee-ii-stick-dev-path-change-configuration-problem/411424.

Hi Folks, I've been searching the forum and I still have a few questions. I'm trying to prepare for the worst case scenario which would result in me having to rebuild my unraid system from scratch (and of course, have no data loss). From forum posts I've read, I see "Community Applications" recommended to backup flash and files. I have this plugin but don't see any option where I can actually perform a backup of the flash/array files... Am I missing something? Thanks!
