Hello, I've a strange issue with my brand new DS 916+, I had previously a HP N40L with xpenology and after more than 5 years of good services I decided to buy a real synology The RAM usage of my DS916+ (8Gb) is increasing over weeks and finally the nas is crashing. After couples of investigations it seem to be related to slab memory usage that increasing dramatically. Bellow you will find the result of some commands related to slab functionnality. We can see that "cred_jar" is using most of the memory and it's "Unreclaimable" After a reboot of the nas the memory start at more or less 20% of usage and is incresing over 2 or 3 weeks to more than 90%. ash-4.4# cat /proc/meminfo MemTotal: 8093200 kB MemFree: 1224388 kB Buffers: 9892 kB Cached: 948788 kB SwapCached: 42332 kB Active: 652760 kB Inactive: 1078964 kB Active(anon): 384036 kB Inactive(anon): 885104 kB Active(file): 268724 kB Inactive(file): 193860 kB Unevictable: 1184 kB Mlocked: 1184 kB SwapTotal: 6954924 kB SwapFree: 6654860 kB Dirty: 136 kB Writeback: 0 kB AnonPages: 742560 kB Mapped: 312764 kB Shmem: 494924 kB Slab: 4547088 kB SReclaimable: 77560 kB SUnreclaim: 4469528 kB KernelStack: 13104 kB PageTables: 60516 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 11001524 kB Committed_AS: 7307152 kB VmallocTotal: 34359738367 kB VmallocUsed: 525616 kB VmallocChunk: 34359113488 kB DirectMap4k: 19200 kB DirectMap2M: 8282112 kB ash-4.4# slabtop --sort c Active / Total Objects (% used) : 37272947 / 37437940 (99.6%) Active / Total Slabs (% used) : 1131412 / 1131432 (100.0%) Active / Total Caches (% used) : 147 / 269 (54.6%) Active / Total Size (% used) : 4192989.21K / 4223942.65K (99.3%) Minimum / Average / Maximum Object : 0.02K / 0.11K / 4096.00K OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 18127720 18127720 100% 0.19K 906386 20 3625544K cred_jar 18155200 18155200 100% 0.03K 162100 112 648400K kmalloc-32 494020 493871 99% 0.19K 24701 20 98804K kmalloc-192 30919 11710 37% 0.55K 4417 7 17668K radix_tree_node 25398 24524 96% 0.63K 4233 6 16932K inode_cache 64008 61953 96% 0.18K 3048 21 12192K vm_area_struct 57920 40462 69% 0.19K 2896 20 11584K dentry 670 655 97% 16.00K 670 1 10720K kmalloc-16384 272 272 100% 32.00K 272 1 8704K kmalloc-32768 2133 2133 100% 4.00K 2133 1 8532K kmalloc-4096 107484 103436 96% 0.07K 2028 53 8112K btrfs_free_space 864 862 99% 8.00K 864 1 6912K kmalloc-8192 4098 4096 99% 1.20K 1366 3 5464K raid5-md2 3768 2229 59% 1.19K 1256 3 5024K btrfs_inode 53900 10859 20% 0.09K 1225 44 4900K btrfs_extent_state 70092 60033 85% 0.06K 1188 59 4752K anon_vma_chain 5705 5676 99% 0.70K 1141 5 4564K proc_inode_cache 14745 10194 69% 0.25K 983 15 3932K filp 3368 3311 98% 1.00K 842 4 3368K kmalloc-1024 4055 4020 99% 0.70K 811 5 3244K shmem_inode_cache 46551 35428 76% 0.06K 789 59 3156K kmalloc-64 2244 1915 85% 1.02K 748 3 2992K ext4_inode_cache 43282 32811 75% 0.05K 646 67 2584K anon_vma 5096 5096 100% 0.50K 637 8 2548K kmalloc-512 8151 1422 17% 0.30K 627 13 2508K btrfs_delayed_node 18060 6824 37% 0.12K 602 30 2408K kmalloc-128 20094 20072 99% 0.11K 591 34 2364K sysfs_dir_cache 962 962 100% 2.00K 481 2 1924K kmalloc-2048 880 877 99% 1.97K 440 2 1760K task_struct 5605 1205 21% 0.20K 295 19 1180K btrfs_extent_buffer 9 9 100% 128.00K 9 1 1152K kmalloc-131072 405 385 95% 2.06K 135 3 1080K sighand_cache 7440 3999 53% 0.12K 248 30 992K kmalloc-96 273 256 93% 2.06K 91 3 728K idr_layer_cache 860 811 94% 0.69K 172 5 688K sock_inode_cache 5550 2592 46% 0.10K 150 37 600K buffer_head ash-4.4# cat /proc/slabinfo | grep -i cred_jar cred_jar 18127976 18128000 192 20 1 : tunables 120 60 8 : slabdata 906400 906400 0 I tried to contact the synology support but the only answer is "Grant us remote control" and I don't want to let them access my private NAS Any help is welcome, thanks guys 😎

Did you update from previous version or it's a fresh install ? I'm curious because I have an N40L too Thanks mate !

Un grand merci à Lionel0676, testé et approuvé sur mon N40L ce week-end !

Hello all, did someone test this tutorial on an HP N40L ? Rgds.

Hello All, could someone help me to integrate "Usb 1.1 ohci-hcd driver" on my N40L ? (jun's release). I was waiting for the new quicknick release that should integrate it but I was thinking to try it myself I'm pretty happy with the Jun's release, only missing my USB UPS due to this driver not integrated.

already the case today with Jun's loader, at least with my N40L ...

+1

Thanks in advance for that jun

I don't know if it can help for the UPS issue on HP microserver : From viewtopic.php?f=2&t=915&start=10

Hey jun, do you think that it's possible to integrate the driver for USB chipset of the N40L into your image ? +1 Just a tiny up If someone want to help on that and need more information don't hesitate to ask ...

C'était sous entendu en fait qu'il faut utiliser le script ci-dessus, en effet de base après l'installation le CPU est au max. Désolé si ce n'était pas claire.

Youpie le portage a été fait et fonctionne très bien. Savez-vous si l'économie d’énergie est intégrée? Et si un support pour les UPS est prévu? Je ne sais pas si quelqu'un à répondu mais je confirme que sur un N40L la fonction d'économie d’énergie marche impeccable

Hey jun, do you think that it's possible to integrate the driver for USB chipset of the N40L into your image ?

Hello All, I have updated my HP N40L successfully, thanks for the authors of this loader !!! Just a "little" thing regarding the UPS, nothing was detected and it was working before in 5.2 (USB UPS) Any idea ?

Up to be over the spam message

Hello all, Since yesterday I have a very strange issue with my Xpenology (HP N40L). Everytime I do a "ls" on the / directory all the services of my NAS was gone and not working, Samba, Syno webpage, all ... I can reboot the NAS and everything is back again until I connect in SSH and do "ls" in / again There is nothing special in the logs, it seem that when the thing happen the system create a new folder for /var and /run : for example if I'm doing a ls on this new /var or /run folder I can find "new" files since my crashing command. I can't enter the 2 strange folders with very strange characters "no such files or directory" I already tried to unmount the partition and do fsck but the same... That's very very strange, that's not a big deal as for the moment I don't need to use the SSH Any idea is welcome

So you're telling me we can just use the update in the control panel now... ? I do it yesterday, I don't know if it's a new supported feature of nanoboot but it work

I did the update from 4493 to update 1 directly from the syno interface without ssh command It's a new feature of nanoboot ? It's cool

Hello all, I recently updated from gnoboot to latest nanoboot with DSM 4493 but I noticed a decrease of my network speed. Before update a copy from my HP N40L was 120MBs approx and now 70-75MBs Any idea ? It's not critical but annoying. Thanks guys.

Hello All, did someone test with an HP N10L ? If I want to migrate from gnoboot (DSM 5.0) to this version is possible ? Thanks mate

Do you know if nanoboot is working with an HP N40L ?

Hello gnoBoot, any idea on this topic : viewtopic.php?f=2&t=2966 ? Don't hesitate if you want to have some logs or whatever ...

I don't use a serial number generator for my installation of DM5, maybe can I try to change the serial number ?

No success any other idea ?

You mean to access the DSM through http://ipofdsm:5001 will solve this issue instead of https://.... ?
