mdadm issue

Just rebuilt a C6 box last week as C7. Four drives, and sda and sdb for root, with RAID-1 and luks encryption. Layout: lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 931.5G 0 disk ├─sda1 8:1 0 200M 0 part /boot/efi ├─sda2 8:2 0 1G 0 part /boot ├─sda3 8:3 0 500.1G 0 part │ └─md127 9:127 0 500G 0 raid1 │ └─luks-5e007234-cd4c-47c6-b305-734f353a4405 253:0 0 500G 0 crypt / ├─sda4 8:4 0 4G 0 part │ └─md126 9:126 0 4G 0 raid1 │ └─luks-9dd9aacc-e702-43d9-97c2-e7e954619886 253:1 0 4G 0 crypt [SWAP] └─sda5 8:5 0 426.2G 0 part └─md125 9:125 0 426.1G 0 raid1 sdb 8:16 0 931.5G 0 disk ├─sdb1 8:17 0 500.1G 0 part │ └─md127 9:127 0 500G 0 raid1 │ └─luks-5e007234-cd4c-47c6-b305-734f353a4405 253:0 0 500G 0 crypt / ├─sdb2 8:18 0 4G 0 part │ └─md126 9:126 0 4G 0 raid1 │ └─luks-9dd9aacc-e702-43d9-97c2-e7e954619886 253:1 0 4G 0 crypt [SWAP] └─sdb3 8:19 0 426.2G 0 part └─md125 9:125 0 426.1G 0 raid1 The problem is md125. System gagged on bringing it up when I rebooted, until I commented it out of fstab. Now, cryptsetup gives me the same UUID as I have in /etc/mdadm.conf. The entry in /etc/crypttab looks identical to the RAIDs for root and swap, but nope. I was able to d an mdadm --assemble -u $(UUID from mdadm.conf), and then a cryptopen luks... but never got anything in /dev/mapper. I'm still fighting - any thoughts? (No, I can't reboot again, like I did this morning, it's now serving four important home directories from another pair of drives with RAID 1.) mark

Re: [CentOS] CentOS 8 partiitioning for reliability
by Nathan Duehr 24 Jul '19

Honestly, something that big I put a NAS variant on it like OpenMediaVault, and CentOS and other distros in virtuals for jobs.

some questions about tuned ...
by hw 19 Jul '19

19 Jul '19

Hi, what is the point of running tuned as a daemon when dynamic tuning is disabled? What is the point of enabling dynamic tuning, especially when using the supplied profiles like throughput-performance? I haven't customized those by specifying any thresholds, and I don't see any point in doing things like dynamically changing disk schedulers or CPU governors depending on something recognized by tuned. Why is there no measurable difference in power consumption between using the powersave, throughput-performance and virtual-host profiles but a very noticeable difference in performance? The difference in performance appears to depend mainly on which CPU governor is used. For example, you can make a customized profile from throughput-performance that uses the powersave governor, and performance will be very much as if using the powersave profile. Since there is no measurable difference in power consumption, why would I want to use profiles and/or CPU governors that supposedly save power and decrease performance?

SELinux settings for directory shared via NFS and samba?
by hw 19 Jul '19

19 Jul '19

Hi, what do I need to do to share the same directory with both NFS and samba? SElinux requires 'samba_share_t' for samba and 'nfs_t' for NFS, and AFAIC I can't set both at the same time on a directory.

cryptsetup
by mark 18 Jul '19

18 Jul '19

On a just-built C 7 box, I've got this: boot, boot_efi, /, swap, and export. Now, the last three are encrypted. For /, I'm trying to add an escrow key. df -h shows me that / is /dev/dm-1. However, when I use cryptsetup luksAddKey /dev/dm-1, it just comes back, without prompting me for a password. What am I missing? mark

Missing PHP Redis package in Software Collections ?
by Nicolas Kovacs 18 Jul '19

18 Jul '19

Hi, I'm currently fine-tuning OwnCloud on a CentOS 7 server. To configure transactional locking, I need Redis with the corresponding PHP module. Until recently the server has been running PHP 7.1. I simply installed the 'redis' package as well as 'sclo-php71-php-pecl-redis', started and/or restarted a handful of services, and things worked perfectly. Now I'm upgrading my server to PHP 7.2, and it looks like there's one package missing in the Software collections. See for yourself: $ yum search php | grep sclo | grep redis sclo-php70-php-pecl-redis.x86_64 : ... sclo-php70-php-pecl-redis4.x86_64 : ... sclo-php70-php-phpiredis.x86_64 : ... sclo-php71-php-pecl-redis.x86_64 : ... sclo-php71-php-pecl-redis4.x86_64 : ... sclo-php71-php-phpiredis.x86_64 : ... sclo-php72-php-pecl-redis4.x86_64 : ... sclo-php72-php-phpiredis.x86_64 : ... As you can see, PHP 7.0 and PHP 7.1 both have three Redis-related packages, whereas PHP 7.2 only has two. It looks like I need the sclo-php72-php-pecl-redis package, but it's nowhere to be found. Any suggestions ?
