I'm trying to install an LSI 9341-8i raid card in a workstation (MSI TRX40 pro 10G, linux kernel 5.8.0-63-generic) and am running into trouble possibly at getting the linux driver operational. I am able to get into the card Bios and set the drives as JBOD (for use with ZFS). I've downloaded and installed the latest linux driver from Broadcom. The module shows up in lsmod: megaraid_sas 163840 0 In lshw, the card appears as "unclaimed": *-raid UNCLAIMED description: RAID bus controller product: MegaRAID SAS-3 3008 [Fury] vendor: Broadcom / LSI physical id: 0 bus info: [email protected]:03:00.0 version: 02 width: 64 bits clock: 33MHz capabilities: raid pm pciexpress vpd msi msix cap_list configuration: latency=0 resources: ioport:3000(size=256) memory:e8200000-e820ffff memory:e8100000-e81fffff memory:e8000000-e80fffff And during boot, dmesg shows: [ 0.953207] megaraid_sas: loading out-of-tree module taints kernel.

context. our server have a small disk, we need to grow /home to store more thinks. /home already have files we back it up. we add another disk to the server, and mount /dev/sdb1 /home and restore the back up to /home so now /home point to /dev/sdb1 instead of sda1. but now i need to see the files from /home but from sda1 and don't have the option to umount /home i know if i umount /home i will se the "old" home folder from sda1 but i don't have the option because the server is productive now but i need the data. ​ Questions How can i "mount?" o access (if that's the term) /dev/sda1/home folder to check the old files. can't reboot, can't umount the actual /dev/sdb1/home, need to be done in Hot submitted by /u/czumaa [link] [comments]
